G. Equilibrium - resultant = 0 N

 

 

 

 

Ex 1)

 

 

 

At Equilibrium:  

 

 

Fnet = 0, a = 0

 

 

 

Velocity is Constant

(rest or constant v)

 

 

Ex 2) Could the forces of 8 N, 6 N and 4 N ever produce a state of equilibrium?

 


If so, find the resultant of the forces 4 N and 6 N. 

 

 

Answer:

 

Yes, resultant of the forces 4 and 6 would have to be 8 N

 

 

 

 

Ex 3) Could the angles of these forces ever be arranged to produce equilibrium?

 

 

 

 

 

 

NO

 

 

4 N and 5 N have a range of possible
resultants of 1 N and 9 N

 

 

 

 

 

 

Could these forces ever
be in equilibrium?

 

 

 

 

 

 

 

No,

 

50 N & 15 N have a
range of 65 N - 35 N
