Question

The movement of the pin P is guided by the two grooves A and B. At the moment illustrated in the figure, A has a speed of 0.2 m/s towards the right with a deceleration of 0.70 m/2, and B moves downward with a speed of 0.2 m/s and a deceleration of 0.35m/2. For this moment, determine,

- The speedand the acceleration aof the pin P

- The ' normal ' and ' tangential ' acceleration of the pin P in the system of coordinates tangential and normal ( t-n )

- The radius of curvature of the trajectory of the pin P at the considered moment.

Explanation / Answer

speed =0.2i-0.2j acc =-0.7 i+0.35 j
