If q [1.5, 1.0, 2.1, 4.3]" x 10-2 ii, determine the following: a) the vector q' b) the stress in the element c) the k matrix d) the strain energy in the element. E = 30 x 10° psi A = 2.1 in.? 2 (50.0,40.0) 1 (10.0, 10.0) 1. (20 %) Consider the truss element shown in figure below. The x-, y- coordinates of the two nodes are indicated in the figure.
