Consider the bar shown in Fig. P3.1 . Cross-sectional area A2 = 1 in.2 , and Young’s modulus E = 2.3 * 106 psi. If q1 = 0.05 in. and q2 = 0.06 in. , determine the following (by hand calculation):

(a) the displacement at point P ,

 (b) the strain P and stress s ,

 (c) the element stiffness matrix, and

 (d) the strain energy in the element.
