For translational equilibrium, the sum of force components along two perpendicular axes must be:
AZero
BEqual
CLarge
DSmall
Answer & Solution
Correct answer: A. Zero
1. Translational equilibrium means no net push in any direction.
2. Resolving along two axes captures the whole plane.
3. The sum of the components of the forces along any two perpendicular axes in the plane must be zero.
4. So the answer is zero.
