Resultant of Many Forces

 

1.         Find the sum of all Horizontal Components (TH)

2.         Find the sum of all Vertical Components (TV)

3.         Use Pythagoras to find Resultants

4.         Use tan to find the angle

 

eg.1

 

1.          

2.          

3.          

 

4.          

 

OR:

 

eg.2     

A = ai + bj

B = ci + dj

C = ei + fj

D = gi + hj

 

then

1.         TH = (a + c + e + g)i

2.         TV = (b + d + f + h)j
