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.




  • vO = 5 i m/s
  • aO = -2 i m/s2
  • r = 0.6 m



  • vA, vB and vC
  • aA, aB and aC


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.
