Q 4. The mine car and its contents have a total mass of 6000 kg and a centre of gravity at G. If the coefficient of static friction between the wheels and the tracks is u = 0.4 when the wheels are locked, find the normal force acting on the %3D /0.15 m front wheels at B and the rear wheels at A when the brakes at both A and B are locked. Does the car move? [Ans. NA = 16.5 kN, Ng =42.3 kN, the car does not move]

Hello good evening, Permission, i have a question in my homework. The following bellow is question. Please advice. Thank you Regards,Irfan A 132-lb cabinet is mounted on casters that can be locked to preventtheir rotation. The coefficient of static friction between the floor and each caster is 0.30. Assuming that the casters at both A and B are locked, determine :(a) the force P required to move the cabinet to the right, (b) the largest allowable value of h if the cabinet is not to tip over.
