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 uniform sheet of metal 6ft square weighs 60lb. If the following weights are hung on each corner of the square in a consecutive manner: 20Ib at A, 60lb at B, 80lb at C, & 40lb at D, find the center of gravity of the system.

Find the reactions at the support

Two spheres, each 1.20 m in diameter, weighs 4kN and 12kN respectively. They are connected with a short rope and placed in water. Find the tension in the rope in kN

A person is sitting with one leg outstretched and stationary, so that it makes an angle of 30.0° with the horizontal, as the drawing indicates. The weight of the leg below the knee is 34.5 N, with the center of gravity located below the knee joint. The leg is being held in this position because of the force M→ applied by the quadriceps muscle, which is attached 0.100 m below the knee joint (see the drawing). Obtain the magnitude of M→.

Cords are looped around a small spacer separating two cylinder each weighing 400kn and pass over a frictionless pulleys to weights of 200KN and 400kn. Determine the angle and the pressure N between the cylinder and smooth horizontal surface

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.

Q4: of a car غطاء محرك The i Jul. The bonnet is held open at an angle of 60° to the horizontal by a vertical force V applied at one end of the bonnet (shown on the diagram). The long, has a weight of 25 N and its center diagram shows the open bonnet bonnet is 0.90 m of gravity G is 0.35 m from the hinge at O. 1) On the diagram, draw and label the two forces other than V acting on the bonnet. By taking moments about A, Proof that the vertical 2) force V applied at the end of the bonnet is 9.7 N. 3) Calculate the magnitude of the force acting at the hinge ON.

A man on the wire singing "Man on a Wire" while practicing for his circus show has reached the center of the rope, creating a dip on the center angled at 63.2 degrees. If the mass of the man is 49.55 kg and the tension force that can be handled by the wire is 449.77N, would the wire break? Show the tension caused by the man hanging on the wire.
