What is Newton's second law of motion?

Newton's second law states that $F = ma$, where $F$ is the total of the forces acting on the system, $m$ is the mass of the system, and $a$ is the acceleration of the system. Signup and view all the answers

What does it mean for a system to be in static equilibrium?

A system in static equilibrium has zero acceleration, meaning it is either at rest or its center of mass moves at constant velocity. Signup and view all the answers

What is the equation for the summation of moments acting on a system in static equilibrium?

The equation for the summation of moments acting on a system in static equilibrium is $M = I\alpha = 0$, where $M$ is the total moment, $I$ is the moment of inertia, and $\alpha$ is the angular acceleration. Signup and view all the answers

What happens to the forces and torque acting on a system in static equilibrium?

For a system in static equilibrium, the total forces and torque acting on the system are balanced and equal to zero. Signup and view all the answers

How is statics related to the analysis of force and torque in a physical system?

Statics is the branch of classical mechanics that is concerned with the analysis of force and torque acting on a physical system that does not experience acceleration, but rather, is in equilibrium with its environment. Signup and view all the answers
