Chapter 5, Problem 5/144 The disk rolls without slipping on the horizontal surface. If the disk has a clockwise angular velocity of wo-21 rad/s and a counterclockwise angular acceleration of 3.6 rad/s2 determine the veloclty and acceleratlon of pln A relatlve to the slotted member BC and the angular velocity and angular acceleratlon of BC. The value of r is 225 mm. Neglect the distance from the center of pin A to the edge of the disk. The relative velocity...

The telephone-cable reel rolls without slipping on the horizontal surface. If point A on the cable has a velocity vA = 0.75 m/s to the right, compute the velocity of the center O (positive if to the right, negative if to the left) and the angular velocity ω (positive if counterclockwise, negative if clockwise) of the reel. The telephone-cable reel rolls without slipping on the horizontal surface. If point A on the cable has a velocity VA = 0.75 m/s...
The disk rolls without slipping on the horizontal surface, and at the instant represented, the center O has the velocity vo = 2.2 m/s and acceleration 20 = 5.9 m/s2 with directions shown in the figure. For this instant, the particle A has the indicated speed u = 2.4 m/s and time rate of change of speed u = 5.9 m/s2, both relative to the disk with directions shown in the figure. Determine the absolute velocity VA and acceleration a...
Problems 1. (30 points.) A uniform circular disk is rolling without slipping on a horizontal surface with an initial speed of 12 m/s. The disk then rolls without slipping up a ramp of height 3.0 m and length (along the ramp's surface) of 12.0 m. Coming to the end of the ramp, it shoots over the edge and ck to the ground. Calculate the magnitude of the angular velocity the disk will have about its center-of-mass when it hits the...
