Problem 4The semicircular disk has a radius of 0.4 m. At one instant, when 0-60°, it is rotatingcounterclockwise at 0-4 rad/s, which is increasing in the same direction at 1 rad/s². Find thevelocity and acceleration of point B at this instant. (Suggestion: Set up relative velocity andrelative acceleration that way you would for a no-slip disk; remember what I told you to memorizeon the first day of class.) (Answer: B = −2.98î - 0.8ĵ m/s, ãB = 2.45î - 5.74ĵ m/s²)B0.4 myX

A ball bearing is moving radially outward in a slotted horizontal disk that is rotating about the vertical z axis. At the instant shown in figure below, the ball bearing is 3.6 in from the center of the disk. It is traveling radially outward at a velocity of 4.4 in/sec relative to the disk and has a radial acceleration with respect to the disk of 5.3 in/sec? outward. What does the magnitude of 0 (in rad/s2) have to be for the ball bearing to have a total acceleration of zero? Figure is from "Engineering Mechanic An Introduction to Dynamics", McGill and King.

A cylinder of radius 7 = 0.2 m is about to start rolling down an inclined plane. The acceleration of the center of the cylinder is 9.81 sin(0) m/s?. The angular acceleration is 9.81 sin(0)/r rad/s?. Assume 0 = 0.8 rad. What is the magnitude of acceleration of the point on the cylinder furthest from the inclined plane in m/s?. Hint: Since it is about to start rolling, the velocity of the center of the cylinder and angular velocity of the cylinder are still zero at that instant.
