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.

An old wooden telephone pole with a single cross member was blown off center during a recent
storm To temporarily stabilize the telephone pole, a repair crew has attached a cable from the end of
the cross member to an eye-ring stake anchored in the ground. (Eigure 3) If the origin O of a
coordinate system is placed where the pole meets the ground, the point where the cross member is
attached to the pole is A(-1.50, 2.10, 23.9) ft and the point where the cable is attached to the
end of the cross member is B(-1.50,-2.90, 26.9) ft. The cable's direction is
(1.00-1.00-1.00k) and it has a tension of 145 lb. What is M₁, the moment that tends to
twist the telephone pole due to the tension in the cable applied at point B?
