Part 1 If the coefficient of static friction between the conical surface and the block of mass m is μ = 0.3 determine the minimum constant angular velocity so that the block does not slide downwards. Part 2 If the coefficient of static friction between the conical surface and the block is μ = 0.3 determine the maximum constant angular velocity without causing the block to slide upwards.

b) Fig. 3 shows a graph that has variable drive torque and constant load torque. The load (2 torque is 500Nm with average speed of 30rpm. A complete cycle for the system is 3x radian. Determine thickness of the flywheel if you want to reduce the coefficient speed of fluctiation from 0.15 to 0.1. Assume the diameter for the flywheel is 50cm and material used is steel (p = 8050kg/m³) le.. Torque (N-m) cm 750 220 K 2n 3 8h3 3" 3n 8(rad)
