For the assembly shown in the figure, determine the stress in each of the two vertical rods if the temperature rises 40 °C after the load P-50 kN is applied. Neglect the deformation and mass of the horizontal bar AB. Use Ea-70 GPa, α-23.0 um/m·°C, Aa-900 mm, E-200 GPa, α=0.7 um/m·°C, and A-600 mm. Steel 4m Aluminum 3m 3m 3m 3m 50 kN

00:01 Okay, so the area is 500 mm2, l1 is 1 .25 m, l2 is 1 m and l3 is 0 .6 m.
00:09 Now we have delta equal to delta 1 plus delta 2 plus delta 3 which is equal to p1 times l1 over a1 times e1 plus p2 times l2 over a2 times e2 plus p3 times l3 over a3 times e3.
00:32 Here a1 is equal to a2 equal to a3 equal to a and e1 is equal to e2 equal to e3 equal to e...
