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 idealized model of a thin-walled convertible car body cross-section is shown in figure Q16. The effect of doors and windows has been ignored. The car has vertical side walls of thickness t1 and length 1 m and a horizontal base of thickness t2 and length 1.9 m. It is constructed from aluminium with a shear modulus of 24 GPa. t₁ = 15 mm t2 = 15 mm a. For this open section determine the torsional stiffness? Give your answer to 3 significant figures in Pa m4 and non-scientific notation e.g. 10000 rather than 10e05. Do not include units in your answer Note that for an open section, the total area moment JT is the sum over all plates i as given by equation (1) below. Ir = = = Ei bit?

A steel plate 5/16 in. thick is embedded in a horizontal concrete slab and is used to anchor a high-strength vertical cable as shown in the figure below. The diameter of the hole in the plate is 0.75-inches, the ultimate strength of the steel used is 36 ksi, and the ultimate bonding stress between the steel plate and concrete is 300 psi. The designers considered a factor of safety of 3.60 is desired when P = 2.5 kips. Address the following: (a) Identify three potential failure modes for the complete system. For each mode develop a sketch which idealizes the mode of failure. (b) If you where required choose dimensions for the plate ("a" and "b"), how would you size these dimensions? (c) For one of the failure modes identified above, perform an analysis to determine adequate plate dimensions ("a" and "b") to support the required load of 2.5 kips with the established factor of safety. in.

2. Refer to the figure below. In addition to the load at point D, if another load Q (Q=10F) along x direction acts at the center of the right end section of bar OABC, solve for the maximum load F with a safety factor of 2.0 using the maximum shear stress theory. Find the stresses at the origin point O. Assume the yield strength of the steel is 42 kpsi with v=0.3.
