Q

How can you calculate the resultant magnitude and

direction of forces using a scale drawing?

A

● Draw the component forces as scaled arrows, joined tip-to-tail
● Draw a line connecting the two open ends.
● Measure the length of this line and convert into the magnitude.
● Measure the angle between the resultant line and the
vertical/horizontal to find the direction
