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).

Question

Draw the exact resultant force in the figure, indicate its moment of force and direction.

Also, locate its intercepts.

The Howe roof truss shown carries the given loads. The wind loads are
perpendicular to the inclined members. Determine the magnitude of the
resultant, its inclination with the horizontal, and where it intersects AB.
