For a rigid body to be in complete static equilibrium in two dimensions, which set of conditions must be satisfied?
- Fx = 0, Fy = 0, and M = 0
- Fx = 0 only
- M = 0 only
- Fx = Fy only
Answer
A. Fx = 0, Fy = 0, and M = 0
Solution
Equilibrium in a plane requires the sum of forces in each of two directions to be zero, and the sum of moments about any point to be zero.
