The length of the bar is L = 4 ft and the angle θ = 30°. The bar’s angular velocity is ω = 1.8 rad/s and its angular acceleration is α = 6 rad/s2. The endpoints of the bar slide on the plane surfaces. Determine the acceleration of the midpoint G.

Strategy: Begin by applying Eq. (17.10) to the endpoints of the bar to determine their accelerations.
