For the plane stress plate fixed along the left and right
sides and subjected to a uniform temperature rise of 50 F as shown in Figure
P15–17, determine the stresses in each element. Let E = 10

F, and t = 1 4 in. The coordinates (in inches) are shown in the figure. (Hint:
The nodal displacements are all equal to zero. Therefore, the stresses can be
determined from {
} =-{DeT}.)
