Problem 1: The hydraulic cylinder BC exerts on member AB force P directed along line BC. Knowing that must have 600-N component perpendicular to member AB, determine: 1- The magnitude of the force P. 2- The component along line AB. M 45° 30° A C Problem 2: Knowing that a- 20°. determine the tension in: Cable AC. 2-Rope BC. A 5° C (R) to 1200 16 B) Problem 3: The end o the cabl attached to the pole AB, which is strengthen by the guy wires AC and AD. Knowing that une tension in wire AC is 120 lb. determine: 1- The components of the force exerted by this wire on the pole 2- The angle directions(a, ß, force forms with the coordinate axes. y 48° Problem 4: Two forces P and Q are applied as shown. Knowing that the connection is in equilibrium and that the magnitudes of the forces on rods and B are FA=750 lb and FB = 400 1b, determine the magnitudes of P and Q Fr 40 P Problem 5: A transmission tower is held by three guy wires attached to pin A and anchored by bolts at B. C and D Knowing that the tower exerts on the pin an upward vertical force of 1800 1b determine the tension in each wire. y 100 R <_20 ft 25 ft 20 74 ft 60 Problem 6: Collars A and B are connected by 25 inches long wire and can slide freely on frictionless rods. If 60 1b force Qis applied to collar B as shown determine the tension in the wire when x = 9 inches and the corresponding magnitude of the force P required to maintain the equilibrium of the system.
