STEADY STRESSES AND VARIABLE STRESSES IN MACHINE MEMBERS 9
Introduction to the design process – factors influencing machine design, selection of materials
based on mechanical properties – Preferred numbers, fits and tolerances ā Direct, Bending and
torsional stress equations ā Impact and shock loading ā calculation of principle stresses for various
load combinations, eccentric loading ā curved beams ā crane hook and āCā frame- Factor of
safety – theories of failure ā Design based on strength and stiffness ā stress concentration ā
Design for variable loading.
