Q2:

Determine the vertical displacement of joint 6 of the steel truss, shown in

Figure 2, using Work-Energy principles and imaginary unit load. The cross-

section area of each member is A= 200mm² and E=200GPa.

Not:

(a) Determine all required internal actions in the members using the pin-

joint method or the method of sections C

(b) You can use an Excel spreadsheet to calculate deflection once

member forces are calculated.

(c) Compare the deflection with Multiframe
