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).

OU President Harroz is hanging an OU banner outside of Boyd house. The banner is hanging from a bar of length L that is supported by a cable attached a distance L/2 above the end of the bar. There are two options, attach the cable to the end of the bar (blue cable) or at a point somewhere nearer the middle of the bar (red cable). Let Fend be the tension if a cable is attached to the end of the bar and Fmid be the tension if a cable is attached closer to the middle of the bar. (There is only one cable at a time.) Let the mass of the sign be 6.07 kg and the mass of the bar be 4.02 kg. Let the red cable be attached a distance 0.60 L from the right end of the bar. What is the ratio of the forces, Fmid/Fend?
