What is the correct equation for velocity? A. Velocity = displacement / time
B. Velocity = displacement * time
C. Velocity = Displacement - time
D. Velocity = displacement + 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.
