The slotted arm OA forces the small pin to move in the fixed spiral guide defined by r = KO where is measured in radians and the constant K = 3.8 m. Arm OA starts from rest at 0 = 53° and has a constant counterclockwise angular acceleration = 2.9 rad/s². Determine the magnitude a of the acceleration of the pin P when 8 = 129⁰. Answer: a = i m/s²

Question
The slotted arm OA forces the small pin to move in the fixed spiral guide defined by r = KO where is measured in radians and the
constant K = 3.8 m. Arm OA starts from rest at 0 = 53° and has a constant counterclockwise angular acceleration 0 = 2.9 rad/s².
Determine the magnitude a of the acceleration of the pin P when 0 = 129º.
Answer: a = i
m/s²
