Consider a beam of length 10m and negligible mass, modelled as a rigid body in the x-direction from x = 0 and x = 10, that is acted on by two forces as shown in Figure 2. We have that 175N and |F2l = 130N and the angles of F1 and F2 with respect to the horizontal are 01 = 50° and 02 = 20° respectively.
