Static Equilibrium
Key Questions
-
Fairly simple! Don't overcomplicate it.
#SigmaF = 0# #Sigmatau = 0# Why? The object isn't moving! So no net forces or torque must be acting on it.
-
In a static equilibrium, all the forces balance each other and object is either not moving or moving with uniform velocity and hence net force is zero .

Answer:
Static equilibrium means that all the forces acting on a body are equal
#and# operating in a direction exactly opposite to another.Explanation:
My favorite example of static equilibrium is in this video on YOUTUBE:
The equilibrium exists with or without the chairs, but it would be more static without the giggling.
