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 statically determinate truss is one of the early problems addressed in sophomore statics classes. A typical problem is shown in figure below: 2 Fapplied √30° F₁ F3 F2 02 3 L. Hinge Roller The applied force has a magnitude of 1000 N at an angle of 30° from the horizontal, as shown in the figure. The inner angles ₁ and 2 are 45° and 65° respectively. Determine the values of the forces in each member of the truss, and the reactive forces experienced at the hinge and the roller (nodes 2 and 3). Set up the problem using a simultaneous equation system. Use the method of the inverse matrix taught in the lectures. Follow the steps a) to e) as indicated below (assume "S" as the matrix representing the previous system. a) Calculate the matrix of minors of S. b) Calculate the matrix of cofactors of S (name it H) c) Calculate the determinant of S. d) Calculate the Adjoint of matrix of S using adj S = HT e) Calculate the inverse of matrix S using S₁ = adj S/|S|
