Aweightlifter lifts a 250-kg mass 0.5 meters above his head, how much peg does the mass have (note: g=9.8 m/s2)? round your answer to the nearest whole number.

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.

What is the magnitude of the resultant vector round your answer to the nearest tenth
