state two practical applications of the principle of moments?
Answers
The principle of moments states that when in equilibrium the total sum of the anti clockwise moment is equal to the total sum of the clockwise moment. When a system is stable or balance it is said to be in equilibrium as all the forces acting on the system cancel each other out.
Applications of multipole moments
For these potentials, the expression can be used to approximate the strength of a field produced by a localized distribution of charges (or mass) by calculating the first few moments.

Answer:
The principle of moments asserts that the sum of clockwise moments about a pivot is equal to the sum of counterclockwise moments about the same pivot when a body is in equilibrium. (2) The theory of moment must be used since the resultant moment about the pivot is 0.
Explanation:
The sum of the anticlockwise moments is equal to the sum of the clockwise moments if a body is in rotational equilibrium. The algebraic sum of the moments about any location is zero if a body is in rotational equilibrium. The application of the Moments Principle is to determine an object's mass. When you pull on the door handle, the door swings open and shuts on its hinges (the hinges are a pivot). The rotation of the door was a direct result of the force you applied when you pushed it open. One highly effective use of thinking time is to push a door open.
Thus, the net moment around one axis on an item is equal to the total of the individual moments acting along that axis, according to the principle of moments theorem.
