How to design a helical compression spring

Helical spring is a vital element for many machines and most of the time helical compression spring is used rather than helical tension spring. This article will talk specifically about design of helical compression spring. More over, we will not consider buckling for spring design, non circular spring wire and non linear springs here.

Theories of failure for brittle materials (part-3): Maximum principal stress theory

Maximum principal stress theory is useful for brittle materials. Maximum principal stress theory or maximum principal stress criterion states that failure will occur when maximum principal stress developed in a…
