Shows the system used to spin the fan blades. The solid properties of each part or component are shown in Table Q1

Counter clockwise moment M of magnitude 10 N.m is applied to gear A which is initially at est.

Draw the fee-body diagrams of gear A , gear pulley B and the combined pulley C and fan blades.

State all relevant assumptions required in kinematics and kinetics analysis of the system

Evaluate:

The time taken for the angular velocity of the fan blades to reach 1500 rpm the tension in the belt.

The acceleration of point D at the instant when the fan blades reach 1500 rmp.
