Homework Answers
here,
If an object is at rest and is in a state of equilibrium, then we would say that the object is at "static equilibrium."
An object in static equilibrium is unable to move because all the forces acting on it compensate for one another.
the net torque on the object is also zero
so, the correct option is (ZERO)

If the sum of the external forces on an object is zero, then the sum of the external torques on it must also be zero. A) True B) False

I need a good explanation about Torques and Equilibrium a) How does torque relate to force? b) If all torques add to zero, does this imply that all forces also add to zero? c) If all forces add to zero, does this imply that all torques also add to zero? d) If both all torques and all forces add to zero, does this necessarily mean that an object is in static equilibrium? Explain. I will appreciate you hard work.

Determine the reaction forces at A and B 50 N 50 N 2n 80 N 160 N 240 N 15 N 30 N 60 N We have studied static equilibrium of forces acting at a common point, and static equilibrium of forces not acting at a common point but involving moments. Now, we will study static equilibrium of entire objects, with the underlying assumption that the objects cannot move nor change shape. These objects are called rigid bodies. We will...
