Problem 2:

The state of plane stress at a point is shown on the element below. Determine the principal stresses. Also determine the maximum in-plane shear stresses and the orientation of the element upon which they act. Construct Mohr's circle. Represent the state of stress on an element oriented 30^o counterclockwise from the position shown.

Problem 6:

Determine the largest load of w that can be supported if the factor of safety with respect to buckling of member AB is 2.5. Draw the shear and bending moment diagrams for the complete length of beam BC. What is the maximum deflection? Assume that the structure is made of 2024-T4 aluminum and that AB is pinned at its ends for x-x axis buckling and fixed at its ends for y-y axis buckling.
