Effort Required in Lifting load using Power Screw Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effort in lifting load = Load on screw*((Coefficient of friction at screw thread+tan(Helix angle of screw))/(1-Coefficient of friction at screw thread*tan(Helix angle of screw)))
P_li = W*((μ+tan(α))/(1-μ*tan(α)))
This formula uses 1 Functions, 4 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)

Variables Used

Effort in lifting load - (Measured in Newton) - Effort in lifting load is the force required to overcome the resistance to lift the load.
Load on screw - (Measured in Newton) - Load on screw is defined as the weight (force) of the body that is acted upon the screw threads.
Coefficient of friction at screw thread - Coefficient of friction at screw thread is the ratio defining the force that resists the motion of the nut in relation to the threads in contact with it.
Helix angle of screw - (Measured in Radian) - Helix angle of screw is defined as the angle subtended between this unwound circumferential line and the pitch of the helix.

STEP 1: Convert Input(s) to Base Unit

Load on screw: 1700 Newton --> 1700 Newton No Conversion Required
Coefficient of friction at screw thread: 0.15 --> No Conversion Required
Helix angle of screw: 4.5 Degree --> 0.0785398163397301 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_li = W*((μ+tan(α))/(1-μ*tan(α))) --> 1700*((0.15+tan(0.0785398163397301))/(1-0.15*tan(0.0785398163397301)))

Evaluating ... ...

P_li = 393.437532401151

STEP 3: Convert Result to Output's Unit

393.437532401151 Newton --> No Conversion Required

FINAL ANSWER

393.437532401151 ≈ 393.4375 Newton <-- Effort in lifting load
