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 sled of mass 500kg sits at rest on a rough slope that is inclined at 10* to the horizontal. The coefficient of friction between the slope and the sled is 0.3. The sled is held in place by a wire attached to a winch. The tension in the wire is TN. a) Find the maximum possible value of T. A load of mass mkg is added to the sled, and tension in the wire is increased to 5000N in order to pull the sled and load up the slop. Given that the sled and load are pulled a distance of 100m in 80seconds, b) Work out the value of m
You need to move a cubic crate across a rough floor. You pull the crate horizontally using a rope with force F, as shown in Figure 1. The weight of the crate is 700 lb:, its density is 180 lbm/fts, and the coefficient of static friction between the crate and the floor is 0.57. Write an expression for the maximum static friction force fmax (in lb:) as a function of the mass m of the crate. Use Excel to plot fmax(m). Calculate the average pressure of the crate on the floor, in psi. Calculate the minimum force F necessary for the crate to start moving, in lb;. F Figure 1. Moving a crate on a slope.
