A crane in a marble quarry is mounted on the rock walls of the quarry and is supporting a 2300kg slab of marble as shown in the figure. The center of mass of the 700kg boom is located one-third of the way from the pivot end of its 15-m length, as shown.(Figure 1) find the tension in the horizontal cable that supports the boom.

    A bucket crane consists of a uniform boom of mass ?=201 kg and length ?=59.91 ft that pivots at a point on the bed of a fixed truck. The truck supports an elevated bucket with a worker inside at the other end of the boom, as shown in the figure. The bucket and the worker together can be modeled as a point mass of weight 197 lb located at the end point of the boom. One end of a long...

    A quarry crane is used to lift massive rocks from a quarry pit. Consider the simplified model of such a crane shown in the figure. (Figure 1) The ends of two poles are anchored to the ground at the same point (point O). From this point, one pole rises vertically and the second pole rises at an angle. The vertical pole has its free end connected to the ground via an unstretchable, massless rope labeled rope 1. A second rope,...

    a 25 ft long crane supported at its lower end by a pin is elevated by a horizontal cable as shown in the figure. A 300 lb load is from the outer end of the crane. the center of gravity of the crane is 10 ft from the pin( along the length of the crane), and the crane weighs 200 lb. what is the tension in the horizontal cable?

    A crane is made from a uniform rigid boom of length L = 30m and weight w = 400N. The boom is sup- ported by a frictionless hinge at its lower end. Its upper end is attached to a support cable which is fas- tened behind the boom at the same horizontal level as the hinge. Adjusting the length of the support / cable adjusts the angle of the boom. In a particu- 7/TTI IN lar application, the crane is...
