Question 1.
What condition defines translational equilibrium?
Show hintHide hint
Think about forces acting on an object at rest.
Question 2.
In rotational equilibrium, what must be true about the sum of torques?
Show hintHide hint
Consider how a seesaw balances.
3Question 3.
What must be true for a body in translational equilibrium?
- The velocity must be constant
- The net external force is zero
- There are no forces acting
Show hintHide hint
Consider what it means for an object to be at rest.
4Question 4.
Is a book lying still on a table in rotational equilibrium?
- True
- False
Show hintHide hint
Think about the forces acting on the book.
Question 5.
A beam is supported at its center with two weights of 150 N and 200 N placed at different distances from the pivot. Calculate whether the beam is in rotational equilibrium.
Show hintHide hint
Use the distance each weight is from the pivot to calculate their respective torques.
Question 6.
Design a basic structure (like a table) ensuring both translational and rotational equilibrium under a specific load. Explain the forces acting on it.
Show hintHide hint
Consider how the design's geometry can affect stability.
