Find the resultant R of the following forces all acting on the same point in the given directions: 30lb northeast; 70 lb to the south; and 50 lb 20 degrees north of west.

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
