A four wheeled trolley car has a total mass 3000kg. Each axle with its two wheels and gears has a total moment of inertia of 32kgm2. Each wheel is of 400mm radius. The centre distance between the two wheels on an axle is 1.4m. Each axle is driven by a motor with a speed ratio of 1.3. Each along with it gear has a moment of inertia of 16kgm2 and rotates in the opposite direction to that of the axle. The centre of mass of the car is 1m above the rails. Calculate the limiting speed of the car when it has to travel around a curve of 250m radius without the wheels leaving the road.

Two blocks are attached by strings of negligible mass to a physical pulley with two radii R1=027 m and R2=042 m. The strings are wrapped around their respective radii so that the masses can move either up or down. The pulley has a moment of inertia Ipcm=0249 kgm2, and is supported by a bearing with negligible friction. If block 1 has a mass of m1=4.1 kg, block 2 has a mass of m2=1.14 kg, and the tension in the rope connecting block 1 to the pulley is T1p=31.11 N, what is the magnitude of the angular acceleration of the pulley?
