## Overturning Moment Formula

The following formula is used to calculate an overturning moment.

OM = RM / 1.5

- Where OM is the overturning moment
- RM is the righting moment

## Overturning Moment Definition

**What is an overturning moment? **

An overturning moment is a measure of the torque required to make a wall, typically a retaining wall, unstable.

## Example Problem

**How to calculate an overturning moment? **

First, determine the right moment of the retaining wall. This is the amount of torque required to right the wall. For this example problem, the over turning moment is 50 ft-lbs.

Next, use the formula above to calculate the overturning moment.

OM = RM / 1.5

OM = 50 / 1.5

OM = 33,33 ft-lbs
