Engineering Mechanics
3 original lesson summaries in this topic collection.
Topic overview
- On a slope, N = W cosθ and the down-slope component is W sinθ.
- Sliding begins when W sinθ exceeds μW cosθ; at the angle of repose tanθ = μ.
- The angle of friction φ also satisfies tanφ = μ.
- Pushing uphill must overcome W sinθ plus friction acting down the slope.
