Formula Used

Load on screw = Torque for lowering load/(0.5*Mean Diameter of Power Screw*((Coefficient of friction at screw thread-tan(Helix angle of screw))/(1+Coefficient of friction at screw thread*tan(Helix angle of screw))))
W = Mt_lo/(0.5*d_m*((μ-tan(α))/(1+μ*tan(α))))
This formula uses 1 Functions, 5 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

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.
Torque for lowering load - (Measured in Newton Meter) - Torque for lowering load is described as the turning effect of force on the axis of rotation that is required in lowering the load.
Mean Diameter of Power Screw - (Measured in Meter) - Mean Diameter of Power Screw is the average diameter of the bearing surface - or more accurately, twice the average distance from the centreline of the thread to the bearing surface.
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

Torque for lowering load: 2960 Newton Millimeter --> 2.96 Newton Meter (Check conversion here)
Mean Diameter of Power Screw: 46 Millimeter --> 0.046 Meter (Check conversion here)
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 = Mt_lo/(0.5*d_m*((μ-tan(α))/(1+μ*tan(α)))) --> 2.96/(0.5*0.046*((0.15-tan(0.0785398163397301))/(1+0.15*tan(0.0785398163397301))))

Evaluating ... ...

W = 1826.34017586688

STEP 3: Convert Result to Output's Unit

1826.34017586688 Newton --> No Conversion Required

FINAL ANSWER

1826.34017586688 ≈ 1826.34 Newton <-- Load on screw

Load on power Screw given Torque Required in Lowering Load Formula

Define Torque?

Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration. Torque is a vector quantity.

How to Calculate Load on power Screw given Torque Required in Lowering Load?

Load on power Screw given Torque Required in Lowering Load calculator uses Load on screw = Torque for lowering load/(0.5*Mean Diameter of Power Screw*((Coefficient of friction at screw thread-tan(Helix angle of screw))/(1+Coefficient of friction at screw thread*tan(Helix angle of screw)))) to calculate the Load on screw, Load on power Screw given Torque Required in Lowering Load formula is defined as a heavy or bulky object that requires effort to move or lift the load. The effort is an applied force to bring desired change to the position (push or lift) of the load. It acts vertically downwards. Load on screw is denoted by W symbol.
