Acaptive james bond is strapped to a table beneath a huge pendulum made of a 3.0-m-diameter uniform circular metal blade rigidly attached, at its top edge, to a 5.5-m-long, massless rod. the pendulum is set swinging with a 10° amplitude when its lower edge is 3.8 m above the prisoner, then the table slowly starts ascending at 1.0 mm/s. after 25 minutes, the pendulum's amplitude has decreased to 7.0°. fortunately, the prisoner is freed with a mere 30 s to spare. what was the speed of the lower edge of the blade as it passed over him for the last time?

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.
