Me and my partner built this toy car as a simple machine project for science its this wooden car thats like 5 inches and it has wheels with an axle going through, how does this car help make easier i have to choose from these two things, it helps make the distance shorter, the force applied on it. So basically how does this car help increase the distance or something like that
Oh i remember doing that project! Is it the one where you make the simple machines? If it is, it's simple! All you got to do is make a 'car'. step 1: get a box (small), 2: buy push pops,3: punch holes in the box so the push pops make wheels, 4: make a pulley out of string, another small box, and push pops, 5: make a block to be a ledge and make a mini see-saw (lever). You use the pulley to get the 'car' down the wedge, then from the wedge you see the 'car' go down and up the see-saw! Isn't it brilliant! my teacher gave me an A+ on the 'car' and an A+ on the writing. (step by step, how-to) inclined plane and lever is the see-saw, the wheel and axle is the 'cars' wheels, the wedge is the wedge or block, and you built a pulley!
The wheel and axle is a simple machine by definition. It is also basically a form of the lever , another simple machine by definition. The fulcrum is at the axle, center of rotation. One force is through the axle and the other force is through the radius at the ground. You will notice that big wheels have a better mechanical advantage and so are easier to push than small wheels. What makes the wheel a special case is that the lenght or distance of applied force is unlimited. By the way, the pulley is another simple machine by definition and is only a wheel with a rope.
