The bar AB is pin-connected at one end to the slider at A and is pin-connected at the other end at B, which is on the disk D at the location shown. Disk D rolls without slipping over the horizontal surface. At the instant shown, slider A is moving in the direction shown with constant speed vo. At this instant, determine, as functions of R and vo, the angular velocities and angular accelerations of bar AB and disk D. R Avo -X 2R R B R R/2 D
