HW04-#2 ARM OA A pin P is confined by a path r = 3 sin(20) feet in a vertical plane and the slotted arm OA. Arm OA is rotating with a

constant angular velocity (@) of 0.3 rad/s when 0=25°. For this system complete the following: A. Draw a diagram of particle A, including a. the x-y, t-n, and r-0 axes systems as related to the motion in this problem (side view) B. Compute the r, acceleration components of the pin at the given location. Ans: B. are =< -1.0338, 0.6942> ft/s² path equation r-3sin(20) ft Pin- 10=25°
