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.

Question

Shown is the stress-strain curve developed from the tension test of a metal alloy bar. The specimen
used to develop the stress-strain curve has a round cross-section with a diameter of d = 7 mm and a
gauge length of L = 370 mm. Determine the load that must be applied to the specimen to stress the
specimen to it's 0.2% offset yield. Express your answer in kN to the nearest whole kN.
Your written solution must also include the length of the specimen when stressed to the 0.2% offset
yield stress.

Hello, the stress and cycles required for this question is Stress 1 = 420MPa at 7 cycles, Stress 2 = 360MPa at 65 cycles and Stress 3 = 130MPa at 325 cycles. Use the first three cycles (which shows how many cycles at that stress level to failure) to calculate when the specimen will fail if it underwent test of 7 cycles at 420MPa, then undergoes 360MPa for 65 cycles and finally 130MPa at 325 cycles. Will the specimen fail? Please show calculations of failure

To determine the nominal or engineering stress and strain experienced by a specimen of a material while it is subjected to a tension test, and to be able to read important values from a conventional stress-strain diagram obtained from the test. A tension test is being conducted on a steel-rod specimen with a gauge length of L0=50 mm and initial diameter of d0=13 mm. Data were collected to form the conventional stress-strain diagram as shown. From the diagram, f = 506 MPa , e = 689 MPa , g = 585 MPa , and h = 0.146 mm/mm . A) Assuming that the strain remains constant throughout the region between the gauge points, determine the nominal strain ε experienced by the rod if it is elongated to L = 53.0 mm . B) Assuming that the stress is constant over the cross-sectional area and if the tension force used is P = 16.0 kN , find the nominal stress experienced by the rod. C)Determine the force P needed to reach the ultimate stress in the steel-rod specimen.
