Correct
Here we learn how to determine the correct virtual-work equation for displacement in trusses.
Part B
Determine the horizontal displacement of joint Ameasured leftward. Use the method of virtual work
Express your answer to three significant figures and include the appropriate units. Enter positive value if the displacement is leftward and negative value if the displacement is rightward.
