n the treatment of spinal injuries, physiotherapists often use bone pull-out, spine, one of the popular devices for Stryker frames. The fixing feature is shown by fixing the weight W to the neck area of the patient lying on the bed. The friction between the patient and the bed prevents the patient from slipping to a mass of weight 2 if the coefficient of static friction.Patient mal 78.5 kg and bed equal 0.75 tensile strength. What is the most valuable vertebrae in which a patient can lie on the bed without plowing? b) Based on the most tensile conditions in (a), what is the rope tension in each rope fixed to the neck?

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).
