If the sum of all moments about a point A of a body is 0, will it then be 0 anywhere else on the body? (I'm working in 2-D)
That is correct. With respect to your previous post, it depends on the situation, as Russ said in your other thread.kasse said:I assume that it works the other way around: if I know that there's equilibrium, then the sum of all moments around any point is 0.

The "Sum of all moments problem" is a concept in physics that involves calculating the sum of all the individual moments acting on an object. Moments are rotational forces or torques that cause an object to rotate around a fixed point. This problem is important in understanding the overall motion and stability of an object.
The "Sum of all moments problem" focuses on rotational forces, while the "Sum of forces problem" focuses on linear forces. In other words, the "Sum of all moments problem" deals with the rotational motion of an object, while the "Sum of forces problem" deals with the overall motion of an object.
Some examples of the "Sum of all moments problem" in everyday life include balancing a seesaw, opening a door, and turning a steering wheel. In each of these situations, there are multiple moments acting on the object that need to be balanced in order to achieve the desired motion.
To solve the "Sum of all moments problem", you need to identify all the forces and moments acting on the object, as well as their distance from the fixed point. Then, using the principle of moments, you can calculate the sum of all the moments and determine if the object is in equilibrium or not.
The "Sum of all moments problem" is important in engineering because it allows for the design and analysis of stable and balanced structures. Engineers use this concept to ensure that buildings, bridges, and other structures can withstand the forces and moments acting on them without collapsing or becoming unstable.
