The coefficient of static friction between a block and an inclined surface is 0.25. What is the angle of repose (the maximum incline angle at which the block remains at rest without sliding)?
- 22.5
- 75.96
- 14.04
- 28.07
Answer
C. 14.04
Solution
The angle of repose satisfies ( ) = , so = arctan(0.25) = 14.04°.
