Question details

In the design of a timing mechanism, the motion of pin P in the fixed circular slot is controlled by the guide A, which is being elevated by its lead screw. Guide A starts from rest with pin P at the lowest point in the circular slot, and accelerates upward at a constant rate until it reaches a speed of 105 mm/s at the halfway point of its vertical displacement. The guide then decelerates at a constant rate and comes to a stop with pin p at the uppermost point in the circular slot. Determine the n-and t-components of acceleration of pin ρ once the pin has traveled 35° around the slot from the starting position. 24 235 mmm Answers: 1 mm/s2 2 mm/s2
