What is the meaning of resultant?

Answer 1

To leap back; to rebound., To come out, or have an issue; to terminate; to have consequences; -- followed by in; as, this measure will result in good or in evil., To proceed, spring, or rise, as a consequence, from facts, arguments, premises, combination of circumstances, consultation, thought, or endeavor., A flying back; resilience., That which results; the conclusion or end to which any course or condition of things leads, or which is obtained by any process or operation; consequence or effect; as, the result of a course of action; the result of a mathematical operation., The decision or determination of a council or deliberative assembly; a resolve; a decree.

Answer 2

It is the single vector that results from two or more different vectorsacting on the same point. E.g.

If you have a simple crane whose rope runs horizontally from the winch to a pulley then vertically to the load, and you have a 100Newton weight on the hook;

the force in the top part of the rope will be 100N,

that in the vertical part will be 100N;

the Resultant force trying to compress the jibwill be

100 X 1.414N = 141.4N at 45º downwardsinto the floor below the winch.

That 141.4 is square-root of 2, because the two lines of rope are at right-angles to each other as is the force in each, and the forces are equal.

If you draw it as a scale diagram whose scale is in force rather than length units you produce a square - take the diagonal for that is the resultant direction. Being a square of side Sits lengthis S(root-2) by Pythagoras and its diagonalis at 45º to the sides!
