– I would ensure that the meter rules balanced before the readings.
– I would avoid error due to parallax.
i. Total forces in one direction are equal to the forces in opposite direction.
ii. The algebraic sum of the moment of all forces about any point should be zero.
The moment of force at equilibrium point o is equal to,
sum of clockwise moment = sum of anti- clockwise moment
