## When a body is in rotational equilibrium the algebraic sum of the moments about any point is?

The sum of moments about any point is zero.

(Rotational equilibrium – Principle of moments) The vector sum of forces on object is zero..

## What theorem deals with the sum of individual moments on an object?

Lesson Summary The principle of moments , or Varignon’s theorem, states that the net moment about one axis on an object is equal to the sum of the individual moments acting along that axis.

## What are the two components of a moment?

It is defined as the product of the force (F) and the moment arm (d). The moment arm or lever arm is the perpendicular distance between the line of action of the force and the center of moments. The Center of Moments may be the actual point about which the force causes rotation.

## What is Moment example?

A moment is the name for the turning effect that forces exert on objects. For example imagine pushing a door open. You push on the door handle and the door rotates around its hinges (the hinges are a pivot). … The larger the perpendicular distance the larger the turning effect (moment).
