Answer:
net force is 40.8 Lb in direction 50.8 degree South of West
Explanation:
As we know that the three forces are given as
F1 = 30 lb North East
F2 = 70 lb South
F3 = 50 lb at 20 degree North of West
Now we can write in vector form as
now the net force due to above all
magnitude of net resultant force is
direction of the force is along
So net force is 40.8 Lb in direction 50.8 degree South of West
