- Homework Statement
- Wheel C has a mass of 60 kg and a radius of

gyration of 0.4 m, whereas wheel D has a mass of 40 kg and

a radius of gyration of 0.35 m. Determine the angular

acceleration of each wheel at the instant shown. Neglect the

mass of the link and assume that the assembly does not slip

on the plane

- Relevant Equations
- ok

how do I know that both angular accelerations are the same for both wheels here? should I apply relative motion analysis for the acceleration at A(with ##a_x,A and a_y,A##) and B(with ##a_{x,B} and a_{y,B}##) here, or is just a_A=r*alpha_C and a_B = r*alpha_D enough from which a_A=a_B and thus both have the same acceleration. Thanks in advance
