Which scenario would likely result in a higher angle of friction?
28. Which scenario would likely result in a higher angle of friction?
- Surfaces with low mass in contact
- Rough surfaces in contact
- Surfaces with oil applied
- Smooth surfaces in contact
Answer
The correct answer is: B) Rough surfaces in contact
Explanation
Rough surfaces provide more interlocking points and therefore tend to have a higher angle of friction compared to smoother surfaces.
