1.1. The rectangular parallelepiped OABCO'A'B'C' of sides OA = 30 cm, OC = 50 cm and OO' = 40 cm is acted by a system of three forces as in figure 1.1. Knowing that F =10 daN, F = 534 daN and F3-202 daN, compute the resulting force and the resulting moment about point O. 1.2. Consider the rigid prism in Figure 1.2., acted by the forces -P=100 N. If having equal module, ---- a = 0.5 m, find the resulting force moment about point O, M P&P and the resulting A' A N O' B' Figure 1.2. B 1 1 C' C Figure 1.1. X E Az D 0 1 B 4 a 2a C
