5.40 Air flows into the atmosphere from a nozzle and strikes a vertical plate as shown in Fig. P5.40. A horizontal force of 9 N is re- quired to hold the plate in place. Determine the reading on the pres- sure gage. Assume the flow to be incompressible and frictionless. p=? Area = 0.01 m² Area = 0.003 m² FIGURE P5.40 9N

Mechanics of Solids

It is the study of the behavior of solid materials, their characteristics under various circumstances such as variation in external forces, temperature, and other internal factors. It is one of most important study in the field of engineering science, especially chemistry and mechanical engineering. In rigid body, the idealization of the solid body in which deformation is neglected. Deformation is known as the force acting on the solid state system which exerts change in its shape of the body but it continues to be at rest or in a uniform motion but it cannot accelerate. But those solid systems do have elasticity, compressibility and can be bent. This field is very vast since there are wide range of materials around us.
