When the wheel moves along the line on a map that you need to measure, the hand moves around the clock face marked with measuring units – centimeters, inches, etc. All you need to do in the end is to check the map scale and to multiply your data by the denominator in the scale.\u003c\/p\u003e\n\n\u003cp\u003eYou can rely on the curvimeter when planning a hike with your friends or a family trip – it will help you to determine the distance you’d cover to get to your destination.

Some sources say the credit of its invention belongs to the Roman engineer Virtuvius, who describes a very similar device around 23 BC. Others refer to a Chinese scholar, Zhāng Héng. Russian sources suggest that the curvimeter might have been invented by the polymath Mikhail Lomonosov who presumably initially called it “krivimetr”. All in all, the official first curvimeter patent belongs to the English engineer Edward Russell Morris who in 1873 registered “a novel device for measuring distances”.\u003c\/p\u003e\n\n\u003ch3\u003eUse\u003c\/h3\u003e\n\n\u003cp\u003eThe Curvimeter is used to measure the length of curved lines on topographic maps, charts, schemes, and plans.

By moving the dual slider, you can multiply and square numbers from 1 to 12, making the multiplication table fun.\u003c\/p\u003e\n\n\u003ch3\u003eWho invented the Mechanical Addiator and Mechanical Multiplier, and when?\u003c\/h3\u003e\n\n\u003cp\u003eThe UGEARS Mechanical Addiator is a DIY wooden model kit based on an addiator that was invented by a St. Petersburg music teacher, Heinrich Kummer, in 1846. Its simple design and compact size made it a popular mathematical tool in its time. Today this simple, fun mechanism is part of UGEARS' outstanding STEM Lab collection.\u003c\/p\u003e\n\n\u003cp\u003eThe UGEARS Mechanical Multiplier is a fun wooden 3D puzzle based on a children's toy, “Consul the Educated Monkey,” invented in 1915 by William Henry Robertson, an American high school math teacher. Robertson applied for a patent for a toy that ingeniously uses a hinged mechanism to perform simple multiplication, designed \"to stimulate children's interest in the study of numbers.”\u003c\/p\u003e\n\n\u003ch3\u003eUses for The Mechanical Addiator and Mechanical Multiplier\u003c\/h3\u003e\n\n\u003cp\u003eThe Mechanical Addiator is used to add and subtract numbers. To do this, the user enters a number value using the stylus, then uses the stylus to enter a second number. The device then shows the result of the desired mathematical operation, according to where the second number was entered (top row for addition, bottom row for subtraction). But the Addiator is not limited to addition and subtraction—you can also use it to multiply and divide.\u003c\/p\u003e\n\n\u003cp\u003eThe Mechanical Multiplier is a simple and interesting way to learn the “unloved” multiplication tables from 1 to 12, and to understand the simple principle of hinge-lever mechanisms. When the two sliders are moved to various numbers, you will see their product displayed in the window above.\u003c\/p\u003e\n\n\u003ch3\u003eComponents of the Mechanical Addiator and Mechanical Multiplier, and how they work\u003c\/h3\u003e\n\n\u003cp\u003eThe Mechanical Addiator consists of a housing in which four rails or racks are set, with printed values on them. A stylus is used to input values. Numbers are entered from cam slots, and the results are displayed in four center windows. Before starting an addition\/subtraction operation using the stylus, the racks should be set so that all windows display \"0\". The value of the number on which the operation is performed is first entered using the top row of slots; the top slots are then used to add a second number, while the bottom ones are used for subtraction.\u003c\/p\u003e\n\n\u003cp\u003eThe Mechanical Multiplier consists of two sliders which move along a number line (1-12), and a lever system which transfers the movement of the sliders to a “Results” window, which moves along a value field. As you move the two sliders between different number values, the product of their multiplication will appear in the “Results” window. In order to multiply a number by itself (to square it), the right slider should be moved to the extreme right position and fixed at the \"X²\" symbol.\u003c\/p\u003e\n\n\u003ch4\u003eThe Mechanical Addiator consists of:\u003c\/h4\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eHousing\u003c\/li\u003e\n\t\u003cli\u003eRack\u003c\/li\u003e\n\t\u003cli\u003eStylus\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eThe Mechanical Multiplier consists of:\u003c\/h4\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eSliders\u003c\/li\u003e\n\t\u003cli\u003eLever system\u003c\/li\u003e\n\t\u003cli\u003eResults window\u003c\/li\u003e\n\t\u003cli\u003eValue field\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cimg alt=\"Arithmetic kit – educational mechanical model kit\" src=\"https:\/\/assets-ugears.scdn3.secure.raxcdn.com\/image\/catalog\/stem-lab\/mechanisms\/scheme-arithmetic-kit-stem_en.png\"\u003e\u003c\/p\u003e\n\n\u003cp\u003eUgears STEM puzzles are designed to suit different age groups with a special focus on learning component.

It registers repetitive actions. It is an integral part of a device called an “Odometer”. The model has three cylinder gears with numbers from 0 to 9 and a Geneva Drive. This combination allows you to see an interesting mechanical feature: when the reciprocating motion of the click-button using the Geneva Drive mechanism turns into the rotary motion of the cylinder gears with numbers.The Counter provides two options of data registering: click-button on the roof of its body, and a turn handle on its side. Pressing the click-button or turning the handle makes the Counter shift by one place. When the count passes 9, the Geneva Drive catches the next register cylinder and adds it to the count. Altogether, the three-digit display of the Counter can register values from 1 to 999. You can open the front panel of the counter and reset it manually. Try counting steps on your way home.

The Differential was designed to ensure that the drive wheels sitting on the same axle rotate with a different rate and cover different distances at the same time.  This mechanism allows the car to make turns without the wheels skidding, prevents wheel-slip, reduces tyre wear, and makes entering and going out of  turns easier for the driver. Having assembled the Differential, your can unblock it pushing the lever in position 1 (Up) and set both wheels in motion by rotation of the drive gear or the wheel. The Control lever regulates the smooth locking of the left and right wheels independently by turning left or right respectively. In the “down” position of the lever, both wheels are linked in a rigid coupling and can either rotate together (propelled by the drive gear or a wheel) or lock simultaneously (by the lever of the wheel).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhen and who invented it:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe car differential was invented by French engineer Onesiphore Pecqueur in 1825.

Who will hoover today? And, of course, who does the dishes?\u003c\/p\u003e\n\n\u003cp\u003eThose who volunteer to do all these chores have our eternal respect, but what if no one volunteers? The fair way to handle this would be to let chance decide and throw a coin. If you have ever bet on heads or tails, this means you got close and personal with probability theory and its practical application.\u003c\/p\u003e\n\n\u003cp\u003eUgears suggests an alternative to the classic coin solution that is not only elegant and fun but has an extra educational benefit. To all questions there is now the answer with Ugears model Random\u003cbr\u003e\nGenerator of the STEM lab Collection.\u003c\/p\u003e\n\n\u003cp\u003eDIY wooden puzzle Random Generator, as you might have guessed from its name, is a device that generates random numbers and provides different random results based on probability theory. How it does this is exactly what the Ugears STEM model will demonstrate.\u003c\/p\u003e\n\n\u003cp\u003eThe main element of the 3D puzzle Random Generator’s design is a cube with an octahedron inside it that in its turn contains a metal ball to provide weight. This construction is powered by a rack-and-gear drive initiated manually and providing energy through a driven gear that rotates a three-axle gear. This is how the cube with all its contents begins to move, which is important for summoning the magic of randomness. Of course, we can only call it magic until we know the science of it. And to learn it, let us take a closer look at the main structure.\u003c\/p\u003e\n\n\u003cp\u003eThe vertices of the octahedron coincide with the sides of the cube. In this way as the energy of the system expires and it stops moving, gravity suspends the metal ball in the lowest part of the octahedron and due to the inclination of the walls it rolls within, it ends up in one of the octahedron’s vertices pulling in down. Whichever of the vertices turns up in the bottom, the side of the cube it is attached to will be right under it and parallel to the floor. In this way, the side of the cube with the answer will be the one facing up on the opposite side.\u003c\/p\u003e\n\n\u003cp\u003eThe probability to get any of the vertices facing down is virtually the same due to symmetry of the octahedron that rotates freely around the axis of its mass. This leads us to a simple conclusion that the probability to receive one of six answers is 1\/6 or 0.167.\u003c\/p\u003e\n\n\u003cp\u003eEvery side of the cube positioned by the vertex of the octahedron, has a message: one says “YES”, the other “TRY AGAIN”, etc.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003e* An octahedron is a regular polyhedron with eight faces (equilateral triangles) and six vertices.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1291\/5195\/files\/scheme_randomizerEN_480x480.png?v=1667137977\"\u003e\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch2\u003eThe mechanism of the Random Generator is composed of:\u003c\/h2\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eButton\u003c\/li\u003e\n\t\u003cli\u003eRack-and-gear drive\u003c\/li\u003e\n\t\u003cli\u003eOverrunning clutch\u003c\/li\u003e\n\t\u003cli\u003eDriven wheel\u003c\/li\u003e\n\t\u003cli\u003eThree-axle gear\u003c\/li\u003e\n\t\u003cli\u003eCube\u003c\/li\u003e\n\t\u003cli\u003eInternal octahedron\u003c\/li\u003e\n\t\u003cli\u003eWeight\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eUgears STEM puzzles are designed to suit different age groups with a special focus on learning component.

Gear ratio can change automatically, manually or within a pre-set program. The term that most drivers and automobile enthusiasts are more accustomed with is Continuously Variable Transmission, or CVT.

The Reeves CVT was also used by several other manufacturers.\u003c\/p\u003e\n\n\u003ch3\u003eUse\u003c\/h3\u003e\n\n\u003cp\u003eThe CVT is used in mechanisms, in which a continuous range of gear ratios must be changed seamlessly: cars, motor scooters, snowmobiles, quadracycles, conveyors, metal-cutting machines, etc. To have a better idea about how it is used in different types of equipment, try the AR application that comes with the Ugears STEM model.\u003c\/p\u003e\n\n\u003ch3\u003eThe 3D puzzle Variator’s design and how it works\u003c\/h3\u003e\n\n\u003cp\u003eThe mechanical puzzle Variator of the Ugears STEM lab collection is a fully functional wooden replica of a Belt-driven Friction Cone CVT. The Cone CVT varies the drive ratio by moving a wheel or belt up and down the axis of conical roller. In the Ugears model kit  Variator, the belt, powered manually via the reducer, transfers the rotation to the driven cone pulleys. Use the transmission fork to change gears and observe how the speed of the driven cone pulley drops or rises while the drive cone pulley’s speed remains the same.
