Question
Three forces 90 N, 125 N and 50 N act simultaneously at a point on an object at the directions west, south and east respectively. Find the resultant of these forces. (5 pts)
Answers
90W + 50E = 40W
so the resultant is -90i+125j = 154.03 cis125.75° ≈ 154@N35°W
so the resultant is -90i+125j = 154.03 cis125.75° ≈ 154@N35°W
