Question

Wheel and axle is called a continuous lever. State reasons

Answer 1

Answer:

Explanation:

Because there is load effort and fulcrum, it works as a lever. When it is in use the load and effort can vary continuously for 360° on the circumference of the wheel and axle. Hence it is a continuous lever.

Answer 2

Answer:

The wheel and axle are called continuous levers because the fulcrum of the wheel and axle is at the center of it.

Explanation:

The wheel and axle are called continuous levers.

As long spanners or axle produce more turning effect due to the long distance between the fulcrum and line of the action of force.

The wheel and axle is called continuous lever because the load and effort vary continuously $360^o$ .

We know that an ordinary lever can be turned by an effort by an angle less than $90^o$, whereas the wheel and axle can turn $360^o$ continuously. So it is called a continuous lever.

Hence, the wheel and axle is called continuous lever.
