Reading Question 2.10 The hook is subjected to three concurrent and coplanar forces. (Figure 1) Part A Determine the resultant force in newtons. 810i + 180j O810i+780j O 930i + 160j O -90i +180j O-90i+ 780j 30i + 660j Figure

Solution

force in x direction = 600*(3/5)-450 =-90

Force in Y direction =300+600*(4/5) =780.

Therefore, resultant force= -90i+780j
