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

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.
