Which scenario would likely result in a higher angle of friction?

28. Which scenario would likely result in a higher angle of friction?

1. Surfaces with low mass in contact
2. Rough surfaces in contact
3. Surfaces with oil applied
4. 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.
