The general solution to an arbitrary mechanical problem can involve both forces and torques (moments). For any mechanical configuration, if there is no motion, two things must be true:
- the sum of the forces must be zero
- The sum of the torques must be zero
Depending on the specific problem, you might need one of these rules---or both.

I prefer to base everything on fundamentals. With linear motion, if there is a net force on an object, it will accelerate: F = m*a. Same answer for torque (moment): If the sum of all the torques is not zero, then there will be a radial acceleration. How about posting a new question?--ideally with a picture

I remember learning that the sum of forcea and sum of moments are not equal to 0, in a force system, the system can be reduced to a wrench. Am I right?02/06/20
