Angle of ReposeMediumQuestion 30242

Question

The angle of repose is the angle at which a block just begins to slide. If μₛ = 0.5, the angle of repose is approximately:
  1. A
    26.6°
    Correct
  2. B
    30°
  3. C
    45°
  4. D
    63.4°

Correct answer

26.6°

Explanation

At angle of repose: tanθ = μₛ = 0.5. θ = arctan(0.5) ≈ 26.6°.
