Why do we not remove the wheel and turn the axle?

Why do we not remove the wheel and turn the axle?

a boy runs across a football field. Why do we not just remove the wheel and turn the axle? Without the wheel, the axle is useless. Turning the axle directly requires too much effort. The axle can not turn on its own. The wheel balances the axle.

Why does the rear wheel not go around?

Now if I turn to pedals, the chain moves and it drives the sprockets at the back but that’s all, the rear wheel doesn’t go around with them. I had to get a colleague to pick me up and when I described the problem to a Maintenance Engineer at work, he gave the highly technical response…

Why is my rear bike wheel wobbling back and forth?

If it’s wobbling side to side, there are two problems that are possible; Your cup-and-cone bearings could be loose or your wheel could be out of true (slightly buckled.) Take your wheel off and hold the axle. Wobble it up and down a few times. There should be absolutely no movement besides the spinning it’s meant to be doing.

Why do you need a differential in the middle of a drive axle?

Two wheels on a drive axle without a differential in the middle would result in both wheels receiving the same power at all times. Having a differential however, enables each wheel to act individually. Why should you care?

Why do wheels and axles need friction to work?

Wheels eliminate this friction force by using leverage and an axle. They still need friction so that they can “push back” on the ground on which they roll, otherwise slippage occurs.

Why do smaller wheels produce more driving torque?

So for a constant driving torque, smaller diameter wheels produce a greater tractive effort at the axle than larger wheels. This is the force which pushes a vehicle.

How does the diameter of a wheel affect forward motion?

It removes kinetic friction which opposes forward motion when an object is slid and replaces it with friction at the axle/wheel beating. Increasing the diameter of the wheel reduces this friction proportionately.

Why does a freewheel Wobble Up and down?

The freewheel is wobbling for two reasons: The right-left movement is because the threads for the freewheel are not exactly centered on the axle. The up and down is because the threads are not at exactly a right angle to the axle.
