Torque Required while Load is Descending in Screw Jack Solution

Follow our step by step solution on how to calculate Torque Required while Load is Descending in Screw Jack?

FIRST Step Consider the formula

T des = \frac{d m}{2} \cdot W \cdot \tan (θ - Φ)

Next Step Substitute values of Variables

∴

T des = \frac{0.24m}{2} \cdot 1000N \cdot \tan (75° - 12.5°)

Next Step Convert Units

∴

T des = \frac{0.24m}{2} \cdot 1000N \cdot \tan (1.309rad - 0.2182rad)

Next Step Prepare to Evaluate

∴

T des = \frac{0.24}{2} \cdot 1000 \cdot \tan (1.309 - 0.2182)

Next Step Evaluate

∴

T des = 230.517855236424N*m

LAST Step Rounding Answer

∴

T des = 230.5179N*m
