Concept explainers

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

Ø20
R2
The 10-mm thick component in the figure is designed with a fillet and a hole. The load varies from
50 to 10 kN. The following strengths are given: S=390MPA and S,=282MPa. Using the Modified
Goodman Theory, determine the safety factor (assuming proportional loading) for the hole as
well as for the fillet. Select all non-given parameters (e.g., notch sensitivity factor, endurance
limit modifying factors, etc.) by your own – if you can justify your selections, that will be a bonus.
At which location will failure first occur? Will the component fail for infinite life expectation?
Explain in your own words.
If the component is determined to fail for infinite life expectation, lower the midrange and
amplitude of the force applied proportionally up to a level that infinite life can be expected. What
is the value of the force at this level?
