Find the moment of the force along AB about point C by using a determinate to solve (see video 3-21). Recall that forces are sliding vectors and they can be slid anywhere along it's path, this is know as transmissibility. Solve the problem twice (a) using a position vector from C to B, (b) using a position vector from C to A. Did you get the same answer? Ignore the cross sectional dimensions of the members. Hint: See videos 3-05 and 3-06. 1400m A 1480mm 2350mm 870N Answer(s): D. 1100mm 1100
