A ball can be taped to the rim of a disk of radius R. You start spinning the disk about an axis of rotation that goes through the center of the disk, while the disk sits on a flat frictionless tabletop. At some angular speed max the ball detaches. What is the force required to detach the ball from the disk?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius Ďa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature Ďr of its path, both as observed by the nonrotating skydiver.

On a mild saturday morning while people are working inside, the furnace keeps the temperature inside the building at 23degreesc. at noon the furnace is turned off, and the people go home. the temperature outside is a constant 16degreesc for the rest of the afternoon. if the time constant for the building is 3 hr, when will the temperature inside the building reach 18degreesc? if some windows are left open and the time constant drops to 2 hr, when will the temperature inside reach 18degreesc?

Two wooden members of 80 à 120-mm uniform rectangular cross section are joined by the simple glued scarf splice shown. knowing that β = 22° and that the maximum allowable stresses in the joint are, respectively, 400 kpa in tension (perpendicular to the splice) and 690 kpa in shear (parallel to the splice), determine the largest centric load p that can be applied using mohr's circle. (round the final answer to two decimal places.)
