Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.

A hand pushes horizontally with a constant force on two blocks stacked against a wall (u, between finger and block A is zero). The blocks and wall do not accelerate. The mass of block A is greater than that of block B. The coefficient of static friction between the block and wall is the same as the coefficient of static friction between the two blocks. Draw a separate free-body diagram for each block. For each force on your free-body diagrams, be sure to indicate: • the type of force (e.g., tension, weight ...), • the object on which the force is exerted, and • the object exerting the force. a. Rank the magnitudes of the vertical forces that you have shown from largest to smallest. Explain how you applied Newton's second and third laws to obtain your answer. b. Suppose the hand pushes horizontally with a constant force that is twice as large as in part a. Would the friction force exerted by the wall be greater than, less than, or equal to the friction force by the wall in part a?…
