Q1.
If the yield stress (σy) of a material is 375MPa, determine whether yield is
predicted for the stresses acting on both the elements shown below using:
(a) Tresca Criterion
(b) Von Mises Criterion
P
Element A
R
S
Element B
Note: your values for P (vertical load on Element A) should be negative (i.e.
corresponding to a compressive vertical load).
Q. After a puncture a driver is attempting to remove a wheel nut by applying a force
of P KN to one end of a wheel brace as shown in Fig. 1. In cross-section the brace
is a hollow steel tube (see section aa) of internal diameter r mm and external
diameter q mm.
