The vehicle s used to transport supplies to and from the bottom of the 25-present grade. Each par of wheels one at A and the other at B has a mass of 140 kg with a radius of gyration of 100 mm. The total mass of the vehicle s 520 g. The vehicle is released from rest with a restraining force T of 500 N n the control cable which passes around the drum and is secured at D. The wheels roll without slipping.
a) Calculate the inertia of wheel A about its centre in kg.m^2
b) Calculate the inertia of wheel C about its centre in kg.m^2
c) Determine the initial acceleration a of the vehicle in m/s^2
