Question

The mechanical advantage of the wheel and axle is given by MA = Radius of wheel / Radius of the axle.

• A. True
• B. False

Answer 1

The correct option is A True

1. Wheel and axle: A wheel with a rod attached to it is known as a wheel and axle.
   
2. The wheel and axle is a simple machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to another.
3. The mechanical advantage of a simple machine is the ratio of the load overcome to the effort applied.
4. In the case of wheel and axle, the Mechanical advantage is given by
5. In the case of wheel and axle, the mechanical advantage is always greater than
   ,$mechanicaladvantage=\frac{radiusofthewheel}{Radiusoftheaxle}$
6. In the above figure, we can observe that the diameter of the wheel is greater than the diameter of the axle. So the mechanical advantage is always greater than $1$.

Hence, the given statement is true.
