Show hintHide hint
Think about its center of gravity.
Question 2.
Where is the C.G. of a uniform beam located?
Show hintHide hint
Consider how weight is distributed.
3Question 3.
What defines a uniform beam?
- A beam with fluctuating weight
- A beam with even weight distribution
- A beam with only one support
Show hintHide hint
Think about where the center of gravity is located.
4Question 4.
In equilibrium, which of the following conditions must be true?
- True
- False
Show hintHide hint
Recall the definitions of forces acting on beams.
Question 5.
A beam weighs 10 N and has a length of 2 meters. If a weight of 5 N is placed at 0.5 m from one end, calculate the position of the center of gravity of this system and check if it is in equilibrium.

Use ΣM = 0 to analyze the forces and distances involved.
Question 6.
Design a beam that supports varying weights on either end. Discuss how you would ensure that it remains stable and does not tip over.
Show hintHide hint
Think about where the C.G. shifts with weight changes.
