The mechanism shown in figure-5.156 is used to raise a wooden box of mass 50kg .A string is wrapped around a cylinder that turns on an axle.The cylinder has radius 0.25 m and moment of inertia 0.92 `kg-m^(2)` about the axle. What magnitude of the force F applied tangentially to the rotating crank handle is required to raise the box with an acceleration of 0.80m`//`s.Here we can neglect the moment of inertia of the axle and the crank
