Q1
The resultant force of the towbar on the trailer has a horizontal component and a vertical component.
horizontal force = 200 N vertical force = 75 N
Determine the magnitude and direction of the resultant force of the towbar on the trailer by drawing a vector diagram.
Magnitude of force = _______________ N
Direction of force = ________ degrees (4)
-
I drew the horizontal force of 200 N and the vertical force of 75 N to the same scale using a ruler and protractor. ✅
Then I completed the vector triangle by drawing the resultant force from the start of the 200 N force to the end of the 75 N force (arrow pointing from bottom right to top left). ✅
I measured the length of the resultant force and converted it using the scale, and got a value of about 214 N. ✅
I measured the angle between the resultant and the horizontal and got 21°. ✅
Answer: Resultant = 214 N, Direction = 21° from horizontal
