A cubical block rests on an incline plane of μ = 1/√3. Determine the angle of inclination when the block just slides down the inclined plane?
Answer: 30°
Explanation
Since μ = 1/√3, we can use the fact that μ = tan(θ) when the block just slides down the inclined plane.
μ = 1/√3 = tan(θ)
θ = arctan(1/√3)
θ = 30°
