If a number of forces are acting at a point, their resultant is given by

(∑V)2 +(∑H)2 +2(∑V)(∑H)

√[(∑V)2 +(∑H)2 +2(∑V)(∑H)]

√[(∑V)2 + (∑H)2]

(∑V)2 + (∑H)2

(∑V)2 +(∑H)2 +2(∑V)(∑H)

√[(∑V)2 +(∑H)2 +2(∑V)(∑H)]

√[(∑V)2 + (∑H)2]

(∑V)2 + (∑H)2

Engineering Mechanics
The moment of a force

All of these

Is the turning effect produced by a force, on the body, on which it acts

Is equal to twice the area of the triangle, whose base is the line representing the force and whose vertex is the point, about which the moment is taken

Is equal to the product of force acting on the body and the perpendicular distance of a point and the line of action of the force
