Efficiency of Inclined Plane when Effort Applied to Move Body Downward Solution

Follow our step by step solution on how to calculate Efficiency of Inclined Plane when Effort Applied to Move Body Downward?

FIRST Step Consider the formula

η = \frac{\cot (α i) - \cot (θ e)}{\cot (α i - Φ) - \cot (θ e)}

Next Step Substitute values of Variables

∴

η = \frac{\cot (23°) - \cot (85°)}{\cot (23° - 2°) - \cot (85°)}

Next Step Convert Units

∴

η = \frac{\cot (0.4014rad) - \cot (1.4835rad)}{\cot (0.4014rad - 0.0349rad) - \cot (1.4835rad)}

Next Step Prepare to Evaluate

∴

η = \frac{\cot (0.4014) - \cot (1.4835)}{\cot (0.4014 - 0.0349) - \cot (1.4835)}

Next Step Evaluate

∴

η = 0.901002280284652

LAST Step Rounding Answer

∴

η = 0.901
