Find the effort required to lift a load of 50 `kg_(wt)` using a simple machine if its mechanical advantage is

The effort measured in S.I. system in lifting a load through a simple machine is numerically equal to its mechanical advantage. If the mechanical advantage of the machine is increased by 20%, the same effort can lift a load of 12 kgwt. Find the magnitudes of the effort and the original load. (Take g=10 ms^(-2) )

Find the ratio of the load arm to that of the effort arm of a second-order lever if its mechanical advantage is 5.

An inclined plane of length 2 m is used to lift a load of 100 kg_(wt) . The force required to lift the load is 20 kg_(wt) . The height through which the load is lifted is ______ m

A student is able to lift a bag containing books of 20 kg_(wt) by applying a force of 5 kg_(wt) Find the mechanical advantage.

An inclined plane of length 2 m is used to load Maruti cars into a carrier truck. If the body of the truck is at a height of 1 m from the ground, find the effort required to load a car using the inclined plane. The unladen weight of a Maruti car is 600 kgwt (Take g = 10 m s^(-2) )
