Question

The maximum compressive stress should be less than which stress?

(a) Allowable tensile stress

(b) Allowable compressive stress

(c) Allowable shear stress

(d) Allowable bending moment

I got this question during an interview.

Origin of the question is IC Engine in chapter Design of IC Engine Components of Automotive Engine Design

Answer 1

The correct answer is (b) Allowable compressive stress

For explanation I would say: The maximum compressive stress should be less than allowable compressive stress if not the crankshaft tends to bend and wobbling takes place.
