Plane Trusses 1. A pin-jointed truss is loaded as shown in Figure 1. Without obtaining the reactions at the supports‚ determine the magnitude of the forces in members AB and BC and state whether they are in tension or compression. (Ans: Fbc = - 4.81 kN‚ Fab = 2.67 kN) [pic] 2. The truss frame hinged at A and supported by roller at G‚ is subjected to a force of 150 kN at D‚ and 60 kN at F as shown in Figure 2. a) Draw the free-body

I sat on the left side of the plane‚ and it felt great because you know that you are in charge of the beast. I opened my logbook and started my pre-departure check.
