What condition must be met for a surface balanced on a pivot?

Anticlockwise moment = Clockwise moment

What is the formula for calculating a moment?

$M = Fd$

Calculate the moment of a $4N$ force acting $0.4m$ from a pivot.

$1.6 Nm$

What are the units of a moment?

Newton-metres (Nm)

For a balanced system with two forces, which equation applies?

$F_1 \times d_1 = F_2 \times d_2$

How must the force act relative to the distance from the pivot?

Perpendicular

If $F_1 = 25N$ , $F_2 = 8N$ , $d_2 = 20m$ , find $d_1$ for balance.

$6.4m$

Calculate the moment of a $10N$ force acting $0.5m$ from a pivot.

$5 Nm$

A $15N$ force at $4m$ balances a $20N$ force. What is its distance?

$3m$
