The slotted arm OA is pinned at O and as a result of counterclockwise rotation, it drives the peg P along the smooth vertical guide as shown in the figure. If the arm starts rotating from rest at horizontal position and maintains a constant angular acceleration of ??= 1.0 ???/?), determine the magnitudes of velocity and acceleration of P when ? = 1 ???.

Problem 2 The slotted arm OA is pinned at O and as a result of counterclockwise rotation, it drives peg P along the vertical guide as shown in Fig- ure 2. If the arm begins rotating from rest in a horizontal position and maintains a constant angular acceleration of 0 = 1.0 rad/s, deter- mine the magnitudes of velocity and accelera- tion of P when t = 1 sec. r 0 0.5 m A Figure 2: Rotating arm OA in Problem 2.
