Design - BEng 2 - DSGN 215

**Design of a circular shaft subject to Torsion and Bending**

This piece of Java Script uses two failure theories to determine the required
shaft diameter to withstand the specified bending moment and torque for the
material UTS and design factor (factor of safety) entered in the boxes below.

**NB** No account is taken of any stress concentration here, an appropriate
design factor must be entered.

Theories used are:

The maximum shear stress theory (Trseca)

The maximum distortion energy theory (von Mises)
