The sum of the clockwise moments and the sum of the anticlockwise moments differ by a small amount. What is this difference in Nm? Why do they differ? This not a very accurate experiment. Name one improvement would you suggest for the apparatus to improve accuracy. What do you understand by ‘equilibrium’ for the beam in this practical? The meter rule could be fixed in place at the fulcrum and the whole apparatus, with your weights firmly attached, tilted to a constant angle θ to the horizontal, (bench top). Equilibrium is established again. Would this action change the sum of the clockwise moments and the anticlockwise moments? Explain your answer.

3. Method
1. Set up the apparatus as in Fig. 4, with two mass-pieces hanging on one side of the rotation point
and three on the other side.
2. Play around with the positions of the mass-pieces until the metre rule is in equilibrium.
3. Record the masses W1, W2. W3, W4, ete and their corresponding distances from the fulcrum x1,
x2, x3, X4, etc:
4. Note which mass pieces cause clockwise rotation and which cause anticlockwise rotation.
5. Find the sum of the clockwise moments about the fulcrum.
6. Find the sum of the anticlockwise moments about the fulcrum.
