1. The pin in Figure 1 is subjected to two forces, F1= 100 kN and F2= 50 kN. (a) Determine the magnitude and direction of the resultant force acting at point O. [6 Marks] (b) Resolve the resultant force into the components along the u- and y-axes and determine the magnitude of these components. [6 Marks] F 1 F 2 30 V 30 45 Figure 1 > U
