Analysis
To determine theoretically what mass should be suspended from the third pulley, and at
what angle, calculate the magnitude and direction of the equilibrant ( F
E
) by the component
method and the graphical method.
Component Method
On a separate piece of paper, add the vector components of Force A and Force B to determine
the magnitude of the equilibrant. Use trigonometry to find the direction (remember, the
equilibrant is exactly opposite in direction to the resultant). Record the results in Table 1.
Graphical Method
On a separate piece of paper, construct a tail-to-head diagram of the vectors of Force A and
Force B. Use a metric rule and protractor to measure the magnitude and direction of the
resultant. Record the results in Table 1. Remember to record the direction of the
equilibrant, which is opposite in direction to the resultant.
