Instantaneous Center of Zero and Known Velocities - Example Problem 4.4-7

Center O of the disk has the velocity and acceleration shown in the figure. If the disk rolls without slipping on the horizontal surface, determine the velocity and acceleration of points A, B and C for the instant represented.

Given:

• v_O = 5 i m/s
• a_O = -2 i m/s²
• r = 0.6 m

Find:

• v_A, v_B and v_C
• a_A, a_B and a_C

The following video walks you through the solution to this problem. It is suggested that you try solving the problem first and then, if you have difficulties with the solution, watch the video for help.

Locate the disk's IC and then draw the angular velocity, angular acceleration and the velocity directions for points A, B and C. Click on the figure when done.
