Question

Prob. 1(10 points). Determine the magnitude of the component force F and the magnitude of the resultant force $F_R$ if $F_R$ is directed along the positive y-axis. F 45° 200 lb 30° Prob. 2 (20 points) (a) In the below figure, find the magnitude of the resultant force and (b) specify where the resultant force acts, measured from end A (Hint for part (b): to find the location of the resultant force, assume that it acts 'x' meters from 'A'. Then set the sum of the moments of each vertical force about 'A' to be equal to the moment of the resultant vertical force about 'A'). 450 N 300 N 700 N 30° 60° B A 1500 N-m 2 m 4 m 3 m
