In this lesson, we will learn:

- Meaning of translational equilibrium
- Solving problems involving translational equilibrium

- An object can undergo
__translational motion__(motion that changes its position) and__rotational motion__(motion that changes its angle). - An object is in
__translational equilibrium__if the velocity of its translational motion is constant. An object that is not moving or an object that is moving in a straight line at a constant velocity would be considered in translation equilibrium. To be in translational equilibrium, the net force acting on the object must be zero (recall Newton's first law: if no unbalanced forces act on an object, it does not accelerate).

$\Sigma F = 0 N$

or equivalently:

$\Sigma F_{x} = 0 N$ and $\Sigma F_{y} = 0 N$

$\Sigma F:$ sum of all forces, in newtons (N)

$\Sigma F_{x}:$ sum of all force components in x direction, in newtons (N)

$\Sigma F_{y}:$ sum of all force components in y direction, in newtons (N)
