Question

Consider the truss element shown in Figure 1. The x, y coordinates of the two nodes are indicated in the figure. If the displacements at the two nodes are uu = 3 mm and u12 = 1 mm, respectively, determine: (a) displacement at point P, (b) strain, and (c) strain energy in the element U12, X 22 (40mm, 50mm) P (25mm, 30mm) И/ / E = 70 x 103 MPa A = 1200 mm 1 (10mm, 10mm) Figure 1 Note: the strain energy in a bar element is U = EADEMY

Answer 1

Answer:

energy" (and any subsequent words) was ignored because we limit queries to 32 words.
