Calcular el peso del cuerpo que se encuentra suspendido y la tensión en la otra cuerda de la figura 3.50, en los siguientes casos: (a) la cuerda 1 está sometida a una tensión de 100 N, y (b) la cuerda 2 soporta una tensión de 300 N.

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.
