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

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

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

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

Next Step Convert Units

∴

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

Next Step Prepare to Evaluate

∴

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

Next Step Evaluate

∴

η = 0.906829118672584

LAST Step Rounding Answer

∴

η = 0.9068
