Equilibrium

Appeared in Year: 2021

Question

Numeric Answer▾

The wheels and axle system lying on a rough surface is shown in the figure.

The Wheels and Axle System Lying

Each wheel has diameter 0.8 m and mass 1 kg. Assume that the mass of the wheel is concentrated at rim and neglect the mass of the spokes. The diameter of axle is 0.2 in and its mass is 1.5 kg. Neglect the moment of inertia of the axle and assume g = 9.8 in . An effort of 10 N is applied on the axle in the horizontal direction shown at mid span of the axle. Assume that the wheels move on a horizontal surface without slip. The acceleration of the wheel axle system in horizontal direction is m/ (round off to one decimal place) .
