Formula Used
Nominal diameter of screw = Mean Diameter of Power Screw+(0.5*Pitch of power screw thread)
d = dm+(0.5*p)
This formula uses 3 Variables
Variables Used
Nominal diameter of screw - (Measured in Meter) - Nominal diameter of screw is defined as the diameter of the cylinder touching the external threads of the screw.
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.
Pitch of power screw thread - (Measured in Meter) - Pitch of power screw thread is the distance between screw threads and is commonly used with inch-sized products and specified as threads per inch.
STEP 1: Convert Input(s) to Base Unit
Mean Diameter of Power Screw: 46 Millimeter --> 0.046 Meter (Check conversion here)
Pitch of power screw thread: 7.8 Millimeter --> 0.0078 Meter (Check conversion here)
