Use Newton’s law of gravity to calculate the force of gravity between you and Earth. Convert your answer, which will be in newtons, to pounds, using the conversion 4.45 N equals 1 pound (1 lb). What do you normally call this force?

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.
