Consider a beam of length 12m and negligible mass, modelled as a rigid body in the x-direction
from x = 0 and x = 12, that is acted on by two forces as shown in Figure 2. We have that
|Fi| = 45N and |F2|
01 = 40° and 02 = 25° respectively.
= 40N and the angles of Fı and F2 with respect to the horizontal are
