Homework Problem No. 5/155

Suggestions:
  1. Do the velocity and acceleration analysis of link BC using the rigid body equations to find the angular velocity and angular acceleration of link AC. Look back over the Example on page 37 of the lecture notes since that problem is very similar to that of BC.
  2. Use the rigid body acceleration equation relating points C and A to find the acceleration of A: a_A = a_C + alpha x r_A/C - omega^2*r_A/C.

Is it possible to use V(a/d) or A(a/d) due to the piston (point D) being stationary? This could possibly simplify the problem.

You need to use the known magnitude and direction of the velocity/acceleration of C.

D being stationary is a factor in giving us the known information about C; however, it is not additional information.
