Load on Power Screw given Effort Required in Lifting Load with Acme Threaded Screw Solution

STEP 0: Pre-Calculation Summary

Formula Used

Load on screw = Effort in lifting load*(1-Coefficient of friction at screw thread*sec((0.253))*tan(Helix angle of screw))/(Coefficient of friction at screw thread*sec((0.253))+tan(Helix angle of screw))
W = P_li*(1-μ*sec((0.253))*tan(α))/(μ*sec((0.253))+tan(α))
This formula uses 2 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)
sec - Secant is a trigonometric function that is defined ratio of the hypotenuse to the shorter side adjacent to an acute angle (in a right-angled triangle); the reciprocal of a cosine., sec(Angle)

Variables Used

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.
Effort in lifting load - (Measured in Newton) - Effort in lifting load is the force required to overcome the resistance to lift the load.
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

Effort in lifting load: 402 Newton --> 402 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

W = P_li*(1-μ*sec((0.253))*tan(α))/(μ*sec((0.253))+tan(α)) --> 402*(1-0.15*sec((0.253))*tan(0.0785398163397301))/(0.15*sec((0.253))+tan(0.0785398163397301))

Evaluating ... ...

W = 1699.66065184581

STEP 3: Convert Result to Output's Unit

1699.66065184581 Newton --> No Conversion Required

FINAL ANSWER

1699.66065184581 ≈ 1699.661 Newton <-- Load on screw
