Effort Required in Lifting load using Power Screw Solution

Follow our step by step solution on how to calculate Effort Required in Lifting load using Power Screw?

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

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

Next Step Convert Units

∴

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

Next Step Prepare to Evaluate

∴

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

Next Step Evaluate

∴

P li = 393.437532401151N

LAST Step Rounding Answer

∴

P li = 393.4375N
