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).

Write an equation for the bucket and an equation for the cylinder. Your equations should contain the unknowns: abucket, αcylinder and T, the tension in the rope. Using the relation between αcylinder and arope, as well as your two equations, solve for the acceleration of the bucket. *Please include force diagrams* Info: A bucket of water of mass 20.6 kg is suspended by a rope wrapped around a windlass (a solid cylinder) with diameter 0.426 m and mass 18.0 kg . The cylinder pivots on a frictionless axle through its center. The bucket is released from rest at the top of a well and falls a distance 23.6 m to the water. You can ignore the weight of the rope. In addition, assume that the rope rolls off of the cylinder without slipping.

XVI Board Pulled Out from under a Box A small box of mass mi is sitting on a board of mass m2 and length L (Figure 1). The board rests on a frictionless horizontal surface. The coefficient of static friction between Part A the board and the box is ls. The coefficient of kinetic friction between the board and the box is, as usual, less than ls. Find Fmin, the constant force with the least magnitude that must be applied to the board in order to pull the board out from under the the box (which will then fall off of the opposite end of the board).
