A shaft of mass 5•097 t is lifted by two chains from a crane hook. The length of each chain is 4 m and their connections to the shaft are 4 m apart. If the centre of gravity of the shaft is 1•25 m from one of the connections, find the tension in each chain.

A face of a dam adjacent to the water has the shape of an isosceles trapezoid of altitude 20 m, upper base 50 m, and the lower base 40 m. Find the total force exerted by the water on the dam when the water is 15 m deep.

Three hydraulic cylinders control the motion of the backhoe arm and bucket in the given figure. In the position shown, a 18.86-kN horizontal force is applied to the bucket at point L. Assuming the weight of the backhoe arm is negligible compared to forces acting on it, find the force acting on pin A (FA) in kN.

Two squirrels are sitting on a rope as shown. The tension in segment BD is TBD = 6.4 lb at an angle of ϕ = 41 degrees. The tension in segment AB is TAB = 5.568 lb. Find the weight of the squirrel at B and the angle α.

A uniform horizontal beam 5.00 m long and weighing 350 N is attached to a wall by a pin connection that allows the beam to rotate. Its far end is supported by a cable that makes an angle of 50 with the horizontal. If a person weighing 550 N stands 1.50 m from the wall, find the magnitude of the tension T in the cable and the force R exerted by the wall on the beam.

Given that the PE at A is 20 kJ and KE at A is 5.0 kJ. What is the KE at B if the height at B is 2.0 m? (mass= 1000kg)

The telescoping arm ABC is used to provide an elevated platform for construction workers. The workers and the platform together have a mass of 212 kg and have a combined center of gravity located directly above C. Assume 0 = 20°. 5 m 2.4 m B 0.9 m 0.5 m Draw the free-body diagram of the arm ABC.

The gate, which is made up of two welded plates: AO and OC, is articulated in O. Neglecting the weight of the gate, obtain the magnitude of the force and its condition (Tension / Compression) in the AB bar. Barra = bar Agua = water

A wracking ball is suspended below two cables each at an angle with the horizontal. The left cable has tension T1 and angle 37 degrees with the horizontal. The right cable has tension T2 and angle 22 degrees with the horizontal. The Wracking ball has mass 180 kg. Find the magnitude of tension T2.

The Diameters of a small piston and a large piston of a hydraulic jack are 5 cm ad 10 cm respectively. A force of 80 KN is applied on the small piston. Find the load lifted by the large piston when the pistons are at the same level.
