(i)I would avoid draught
(ii)I would avoid parallax error in the reading meter rule
Moment of a force about a point is the product of force and perpendicular distance from the turning point. Moment = F x D The S.I unit is Nm.
(i)The total resultant force must be zero
(ii)The total force in one direction are equal to the total force in opposite direction. That is the total upward force is equal total downward force.
