Question

Determine the mass of a metre rule using a spring balance or by balancing it on a knife edge

at some point away from the middle and a 50g weight on the other side. Next pivot (F) the

metre rule at the 40cm, 50cm and 60cm mark, 104 each time suspending a load L or the left

end and effort E near the right end. Adjust E and or its position so that the rule is balanced.

Tabulate the position of L, F and E and the magnitudes of L and E and the distances of load

arm and effort arm. Calculate MA=L/E and VR = effort arm/load arm. It will be found that MA

VR in the third case. Try to explain why this is so. Also try to calculate the real load and real​
