Moment of a force is defined as
product of the force, F and the perpendicular distance, d moved in the direction of force
Quotient of the force, F and the perpendicular distance, d moved in the direction of force
Product of the force, F and the perpendicular distance, d from line of action of the force to the pivot
Quotient of the force, F and the perpendicular distance, d from line of action of the force to the pivot
In order to satisfy the Principle of Moment for an object in equilibrium, one needs to make sure that
sum of horizontal forces = sum of vertical forces = 0
sum of clockwise moment about pivot > sum of anti-clockwise moments about pivot
sum of clockwise moment about pivot < sum of anti-clockwise moments about pivot
sum of clockwise moment about pivot = sum of anti-clockwise moments about pivot
Correct condition for state of equilibrium in principle of moment is
distance between the two objects in beam balance should be same
resultant force should be zero
the weight of both objects on the beam balance should be same
the tension should be equal on both sides
