Consider the system shown with two masses connected by cable and pulley, with mass B supported on a simply supported beam. The masses mA = 34 kg, mB = 10 kg, and between mass B and the surface of the beam there is a coefficient of friction u = 0.17. C is a fixed pulley anchored to the beam. The beam is of negligible weight, considered as a rigid body, its length and the position of the different elements are indicated in the figure. The masses A and B are considered as particles, therefore, the height h is negligible, as is the dimension of the pulleys. Determine for the position shown, where x = 2.4 m: 6 m 2,5 m TITIT Cable a) The cable tension. pulley beam and massimportant note: this exercise contains 4 subitems.
