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.

The mechanism shown in is used to raise a crate of supplies from a ship's hold. The crate has total mass 54.0 kg. A rope is wrapped around a wooden cylinder that turns on a metal axle. The cylinder has radius 0.04 m and moment of inertia I = 2.4 kg-m² about the axle. The crate is suspended from the free end of the rope. One end of the axle pivots on frictionless bearings; a crank handle is attached to the other end. When the crank is turned, the end of the handle rotates about the axle in a vertical circle of radius 0.12 m, the cylinder turns, and the crate is raised. What magnitude of the force F S applied tangentially to the rotating crank is required to raise the crate with an acceleration of 1.40 m/s?? (You can ignore the mass of the rope as well as the moments of inertia of the axle and the crank.) I0.12 m
