### Sample Learning Goals

At the end of the lesson, students should be able to:

- Predict answer based on concepts learnt
# Balancing Act

- Calculate the total clockwise or anticlockwise moments
- Determine if the beam is balanced
- recall and apply the relationship moment of a force (or torque) = force × perpendicular distance from the pivot to new situations or to solve related problems
- apply the principle of moments to new situations or to solve related problems

### Pre-requisite:

Before this lesson, students should be able to:

- Recall the formula moments = force x perpendicular distance
- Identify the direction of moments
