Analysis: Finding forces in rigid objects

So, you’ve got the vocabulary and you know how to calculate the magnitude of a moment.

Now you will use your new capabilities to analyse the data you obtained from your experiments (or feel free to use the data we’ve supplied in the Downloads section below).

Considering moments opens up new ways for understanding the effects of forces on rigid bodies.

Talking points

• In the balancing experiment the cardboard was pinned in its centre. Explain what would happen if it was off centre; use the concept of moment arm.
