Effort Required in Lowering Load Solution

Follow our step by step solution on how to calculate Effort Required in Lowering Load?

FIRST Step Consider the formula

P lo = W \cdot (\frac{μ - \tan (α)}{1 + μ \cdot \tan (α)})

Next Step Substitute values of Variables

∴

P lo = 1700N \cdot (\frac{0.15 - \tan (4.5°)}{1 + 0.15 \cdot \tan (4.5°)})

Next Step Convert Units

∴

P lo = 1700N \cdot (\frac{0.15 - \tan (0.0785rad)}{1 + 0.15 \cdot \tan (0.0785rad)})

Next Step Prepare to Evaluate

∴

P lo = 1700 \cdot (\frac{0.15 - \tan (0.0785)}{1 + 0.15 \cdot \tan (0.0785)})

Next Step Evaluate

∴

P lo = 119.792912397498N

LAST Step Rounding Answer

∴

P lo = 119.7929N
