A tower crane (Figure 1) must always be carefully balanced so that there is no net torque tending to tip it. A particular crane at a building site is about to lift a m = 3200-kg air-conditioning unit. The crane's dimensions are shown in (Figure 2). The crane's counterweight has a mass of M = 8000 kg . Ignore the mass of the beam. Where must the crane's counterweight be placed when the load is lifted from the ground? (The...

QUESTION 5 (100 marks) (a) A crane is to be used to lift materials at a construction site. The crane is composed of a vertical mast 60 m high, a horizontal jib (B-D) 20 m long and a counter-jib (A-B) 4 m long. The combined weight of the counter-jib plus the counterweight provides a load of 18,000 N at point A. The weight of the jib provides a load of 5,200 N at point c. Note: not to scale 20m...
