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.

Two parts of a machine, both made from steel, are held together by 9 equally-spaced M6 x 1.0 grade 8.8 bolts that are uniformly tightened to provide a total initial clamping force of 77 kN. Each bolt has a proof stress of 600 MPa, and a tensile area of 20.1 mm². The elasticities are such that the joint constant is 0.18. A uniform static tensile load of 36 kN is applied to the entire joint after it has been preloaded. What is the smaller value of either the factor of safety against joint separation or the load factor in this application? Express your answer to a resolution of two decimal places.

The following figure shows the critical position of a crane that supports 2.5 Tons of load by means of a chain. You are delegated the responsibility of building a crane with similar geometric characteristics and load capacity. The diagram of free body of the crane arm can be redrawn as follows. (check the attached image "fbd") Assuming that the crane arm will be made of steel with yield stress sigmaY =220 MPa and that you must consider a safety factor of F.S.=1.5, propose a profile from the following catalog for the manufacture of the crane arm. Ignore the effects of shear forces on this element. On the other hand, it is very important that you consider the effects of axial loads. Commercial profiles for arm construction.
