Worksheet: Equilibrium of a Rigid Body under the Effect of Two Forces

In this worksheet, we will practice solving problems involving a rigid body that is in equilibrium under the effect of two forces.

Q1:

Three forces of magnitudes 16, 19, and 8 newtons, respectively, are acting at a single point. Given that the forces are in equilibrium, find the measure of the angle between the forces of magnitudes 16 and 8 newtons approximated to the nearest minute.

  • A 9 1 3
  • B 9 9 1 3
  • C 1 2 3 4 6
  • D 8 0 4 7

Q2:

Two forces of magnitudes 15 N and 1 5 3 N are acting at a point such that the measure of the angle between them is 1 5 0 . What is the magnitude of the force required to bring this system to equilibrium?

  • A 30 N
  • B 1 5 7 N
  • C 3 0 3 N
  • D 15 N

Q3:

Three forces of magnitudes 16, 10, and 8 newtons, respectively, are acting at a single point. Given that the forces are in equilibrium, find the measure of the angle between the forces of magnitudes 16 and 8 newtons approximated to the nearest minute.

  • A 1 2 0 4 5
  • B 3 0 4 5
  • C 5 4 5 4
  • D 1 4 9 1 5

Q4:

Two forces of magnitudes 22 N and 11 N are acting at a point such that the measure of the angle between them is 9 0 . What is the magnitude of the force required to bring this system to equilibrium?

  • A 1 1 7 N
  • B 1 1 3 N
  • C 33 N
  • D 1 1 5 N
