Figure Q2 shows few loadings applied on bar ABD. Suppose the diameter of the bar is 60mm,
and knowing that P1 = 13kNm, P2 = 5 kNm and P3 = 12 kNm. Values A,B,C are given in Table
Q2.
(a) Find the following stresses at point H.
(i) Normal stress due to P1
(ii) Bending stress and shear stress due to P2
(iii) Normal stress due to P
(b) Determine the state of plane stress at point H and show it on the element.
(c ) Using Mohr’s circle, determine the principal stresses at point H and show the result on
the element.
