A large wrecking ball is held in place by two light steel cables.
a)
A large wrecking ball is held in place by two light steel cables as shown in the figure.
a)If the mass of the wrecking ball is 4040 kg, what is the tension in the cable that makes an angle of 40.0 with the vertical? Take the free-fall acceleration to be = 9.80 .
At one point during its swing, a wrecking ball exerts a tension force of 9800 N on its cable, which makes an angle of 30.0° with the horizontal. The crane's 9.00 m long boom is at an angle of 55° with the horizontal. What is the torque exerted by the wrecking ball on the crane about an axis perpendicular to the page and passing through point P shown in the figure?
