Question 1.
What is the condition for translational equilibrium?
Show hintHide hint
Think about what would happen if forces did not balance each other.
Question 2.
What does it mean for a body to be in rotational equilibrium?
Show hintHide hint
Consider the balance of forces causing rotation.
3Question 3.
What is the main condition for a body to be in rotational equilibrium?
- Total forces are zero
- Total torques are zero
- Both must be zero
Show hintHide hint
Think about stability and how forces and torques interact.
4Question 4.
True or False: A couple can cause both linear and angular motion.
- True
- False
Show hintHide hint
Remember the effect of two opposing forces.
Question 5.
A beam is supported at both ends. A weight is placed 2m from one end. Calculate the force exerted by each support given weights on either side.
Show hintHide hint
Use the moment arm method.
Question 6.
Two masses connected by a pulley system rotate a rigid beam. Calculate the necessary torque to maintain equilibrium.
Show hintHide hint
Think about the tension and radius of the pulley.
