Mechanics of Solids 5
Question 5 Answer the following questions concisely (no more than half a page per question) a What do you understand by strength, stiffness and stability in the Mechanics of Solids context? b sketch, explain and justify mathematically the failure mode of wooden shaft in pure torsion, if the timber grain is aligned with the longitudinal axis of the shaft. c What is/are the possible cause(s) of unsymmetrical bending on a beam? d Explain mathematically why the skin of sausage will normally fail longitudinally (i.e. with a crack running on the longitudinal direction) and not circumferentially (i.e. not split in half) when subjected to internal pressure generated while cooking it on the BBQ e Explain, with your own words, the concept of Fatigue and give two examples of fatigue induced failure.Explanation / Answer
A>>
In materials science, the strength of a material is its ability to withstand an applied load without failure. The field of strength of materials deals with forces and deformations that result from their acting on a material. A load applied to a mechanical member will induce internal forces within the member called stresses when those forces are expressed on a unit basis.
Stiffness is the rigidity of an object
