Q. A wrecking ball (weight = 5400 N) is supported by a boom, which may be supposed to be uniform and has a weight of 3000 N. As the Illustrating shows, a support cable runs from the top of the boom to the tractor. The angle between the support cable and the horizontal is 32°, and the angle between the boom and the horizontal is 48°.
Q. As F is enhancement d, the block would either begin to slide, or begin to tip over. What must be the coefficient of static friction ms so that the block begins to slide rather than tip?
A 210 g, 49 bcm diameter turntable rotates on frictionless bearings at 54 rpm . A 25 g block sits at the center of the turntable. A compressed spring shoots block radically outward along a frictionless groove in the surface of the turntable.
Much of the material making up Saturn's rings is in the form of tiny dust grains having radii on the order of 10-6 m. These grains are located in a region containing a dilute ionized gas, and they pick up excess electrons. As an approximation, sup..
