The robot is programmed so that the 5 kg part A describes the path as below. r = 2 - 4cos(pi/4 t) [m] theta = 1 - 0.5 sin (pi/6 t) [rad] When the external radial directional force is 10 N, find the radial directional acceleration. When the external traverse directional force is 20 N, find the traverse directional acceleration. Find the total force vector at 2 sec.

Solution

Following are the answer of the given problem.

The radial directional acceleration is 56 rad/sec.

Transverse directional acceleration is 32 rad/sec.

Total force 67 kn
