Try again. The figure shows partides 1 and 2, each of mass m, attached to the ends of a rigid massless rod of length L1 + L2, with L1 -2.0 m and L2- 3.0 m. The rod is held horizontally on the fulcrum and then released. What are the magnitudes of the initial accelerations of (a) particle 1 and (b) particle 2?

Explanation / Answer

Net torque = I alpha

(m g L2 - m g L1) = (m L1^2 + m L2^2) (alpha)

9.81 ( 3 - 2) = (2^2 + 3^2) alpha

alpha = 0.755 rad/s^2

(A) a1 = alpha L1 = 1.51 m/s^2

(B) a2 = alpha L2 = 2.26 m/s^2
