Equilibrium of Rigid BodyMediumQuestion 30347

Question

For a rigid body in static equilibrium:
  1. A
    Only ΣF = 0 is required
  2. B
    Only Στ = 0 is required
  3. C
    Both ΣF = 0 and Στ = 0 are required
    Correct
  4. D
    Only linear velocity = 0

Correct answer

Both ΣF = 0 and Στ = 0 are required

Explanation

For complete static equilibrium of a rigid body: net force = 0 (no translation) AND net torque = 0 (no rotation) about any axis.
