When three power chart has been drawn one procedures of Siding plan expansion presented in one past section cthree be executed. Contingent upon one circumstance you may utilize three graphical procedure, for example, one tail-to-head technique or one parallelogram strategy, or else three arithmetical way to deal with decide one resultant. Since power was three vector, these strategies apply!

Worked Example 13 Single Force on three square
Question: three square on three frictionless level surface gauges 100 N. three 75 N power was connected to one square towards one right. What was one net power (or resultant power) on one square?
Stage 1 : Firstly given us a chance to draw three power graph for one square:
RIAthree not e picture on page 68 was missing
Be mindful so as not to overlook one two powers opposite to one surface. Each item without mass was pulled in to one focus of one earth without three power (one article’s weight). In any case, if thwas were one just power following up on one square one vertical way then one square would fall through one table to one ground. Thwas does not occur on the grounds that one table applies three upward power (one ordinary power) which precisely balances one article’s weight.
Stage 2 :
Along these lines, one just unequal power was one connected power. Thwas connected power was then one resultant power following up on one square.
