After an unfortunate accident at a local warehouse, in which a jib crane collapsed and injured a worker, the owners want to determine the cause. A diagram of the jib crane is shown in the image. The horizontal steel beam had a mass of 80.00 kg per meter of length and the tension in the cable was 5 T = 12.56 kN. The crane was rated for a maximum load of 1000 lbs. Consider that d = 5.870 m, S = 0.486 m, x = 2.000 m, and h = 2.250 m. What was the load W₁ on the crane before the collapse? WL = N What was the magnitude of force at the attachment point P? Fp = N P W₁

Mechanical Properties of Solids

There are three types of matter- solid, liquid and gas. Out of them, solids have a rigid shaped and size. The intermolecular forces of attractions in solids are greatest. Mechanical properties are the physical properties of a material which it shows, when it is provided with certain amount of force or load. These properties are to be kept in mind for various purposes. When a force is applied to an object, the object may or may not get deformed depending upon its elastic property. But every time the object develops a restoring force against the force applied. This is commonly known as stress. If the object changes its dimensions due to the force applied it develops strain ( which is the ratio of change in dimension to the original dimension).
