Load on power Screw given Effort Required in Lowering Load Solution

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

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

W = \frac{120N}{\frac{0.15 - \tan (4.5°)}{1 + 0.15 \cdot \tan (4.5°)}}

Next Step Convert Units

∴

W = \frac{120N}{\frac{0.15 - \tan (0.0785rad)}{1 + 0.15 \cdot \tan (0.0785rad)}}

Next Step Prepare to Evaluate

∴

W = \frac{120}{\frac{0.15 - \tan (0.0785)}{1 + 0.15 \cdot \tan (0.0785)}}

Next Step Evaluate

∴

W = 1702.93881263263N

LAST Step Rounding Answer

∴

W = 1702.9388N
