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

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).
The beam shown in the figure below has lateral support at the ends only. The concentrated loads are live loads. Use A992 steel and select a shape.
Do not check deflections. Use C = 1.0 (this is conservative). Suppose that PL
= 20 k.
