Question 2 (15 points): In the mechanism shown below, the crank AB is balanced while links BC and DC are uniform rods of mass equal to 1 kg each. The crank turns counterclockwise (CCW) about A with a constant angular velocity of AB = 100 rad/s. The dimensions of the mechanism are as follows: AB = 2 cm BC 4.2 cm DC = 3 cm EC = 4.2 cm AD = 5 cm A kinematic analysis has yielded the following data: WBC 44.2 rad/s CW WDC 47.5 rad/s CCW αBC = 2814 rad/s² CCW aDc =5315 rad/s² CCW At the instant shown, a tensile force of 10 N exists in the light rod EC. Determine the following: a) (7 points) The D'Alembert force set for links BC and DC. b) (8 points) The magnitude of the bearing reactions at A and D, and the balancing torque on the crank AB.
