Question 1.
What is geometric similarity?
Show hintHide hint
Think about the proportions between a model and a real object.
Question 2.
If a prototype is 50 meters long, how long should a 1:10 scale model be?
Show hintHide hint
Use the scale to find the ratio.
3Question 3.
What does geometric similarity require?
- Same angles
- Different scale ratios
- Both A and B
Show hintHide hint
Think about how shapes maintain their characteristics.
4Question 4.
True or False: A 1:5 scale model of a 50m prototype would be 10m long.
- True
- False
Show hintHide hint
Reflect on how scale ratios work.
Question 5.
A model of a dam is built at a scale of 1:20 to study water flow. If the prototype dam is 80 meters in height, what is the height of the model dam? What implications might there be for studying water flow behavior?
Show hintHide hint
Use the scale ratio for conversion.
Question 6.
Discuss the trade-offs between accurately scaling surface roughness and the feasibility of fabricating models. What approaches might engineers take to address these issues?
Show hintHide hint
Consider practical solutions used in modeling.
