Use virtual work method and determine the following unknowns on the truss system shown below. Use A = 500 mm2 and E = 200 GPa. Show complete and organized solution. Round-off your answers to two decimal places.
GIVEN:
a. 42.0
b. 4.0
c. 9.0
QUESTIONS:
1. Horizontal displacement of joint G due to the applied loads in mm
2. Horizontal displacement of joint G considering that the top chord members experience 60 oC increase in temperature in mm. Use α = 10-6/ oC
PLEASE SHOW YOUR FULL SOLUTIONS AND DRAWINGS. THANK YOU VERY MUCH!! ❤️
