determine the shortest cable ABC that can be used to lift the 910lb beam if the maximum force the cable can sustain is 1500lbs
Homework Answers
here,
the maximum tension in the rope , t = 1500 lbs
weight of the beam , w = 910 lb
let the angle be theta
2 * t * sin(theta) - w = 0
2 * 1500 * sin(theta) - 910 = 0
theta = 17.66 degree
length of the cable ABC , l = 2 * 5 * cos(theta)
l = 2 * 5 / cos(17.66)
l = 10.49 m
the length of cord ABC is 10.49 m

Problem (3) A motor M and a frictionless pulley-cable system are used to lift the 850 lb crate shown at a constant acceleration. The motor has an efficiency of E = 0.6 and the input power to it is 92 hp at the instant when the load has been hoisted s = 15 ft starting from rest. Determine the tension force in the cable. Neglect the mass of the pulleys and cable.
