Question 1.
What happens to beam deflection if the span length is increased?
Show hintHide hint
Think about how weight on a longer beam would affect bending.
Question 2.
How does increasing the applied load affect deflection?
Show hintHide hint
Consider what happens if you add more weight to a scale.
3Question 3.
What is the relationship between span length and beam deflection?
- A) Inversely proportional
- B) Directly proportional
- C) No relationship
Show hintHide hint
Think of how a longer pole would bend more under the same weight.
4Question 4.
True or False: Increasing the modulus of elasticity will decrease beam deflection.
- True
- False
Show hintHide hint
Remember stiffer materials are less prone to bending.
Question 5.
A 12m steel beam (E = 200 GPa, I = 3000 cm^4) has a uniform load of 40 kN. Calculate the deflection at mid-span.
Show hintHide hint
Ensure unit consistency!
Question 6.
Discuss the effects of using different materials for beams in a bridge project. Consider both the deflection and strength aspects.
Show hintHide hint
Investigate properties of steel, wood, and composite materials.
