Acircular-motion addict of mass 81.0 kg rides a ferris wheel around in a vertical circle of radius 10.0 m at a constant speed of 6.10 m/s. (a) what is the period of the motion? what is the magnitude of the normal force on the addict from the seat when both go through (b) the highest point of the circular path and (c) the lowest point?

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.

The slope of a velocity time graph over any interval of time gives the during that interval
