Radius of Journal in Terms of Minimum Film Thickness of Bearing Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radius of Journal = Radius of Bearing-(Eccentricity in bearing+Minimum Film Thickness)
r = R-(e+h_°)
This formula uses 4 Variables

Variables Used

Radius of Journal - (Measured in Meter) - The Radius of Journal is the radius of the journal (which rotates freely in a supporting metal sleeve or shell).
Radius of Bearing - (Measured in Meter) - The Radius of Bearing is the sum of the radius of the journal and radial clearance of a bearing.
Eccentricity in bearing - (Measured in Meter) - Eccentricity in bearing is the displacement of the journal from the bearing.
Minimum Film Thickness - (Measured in Meter) - Minimum film thickness is the lowest amount of the thickness of the oil film formed inside the sliding bearing.

STEP 1: Convert Input(s) to Base Unit

Radius of Bearing: 26 Millimeter --> 0.026 Meter (Check conversion here)
Eccentricity in bearing: 0.011 Millimeter --> 1.1E-05 Meter (Check conversion here)
Minimum Film Thickness: 0.013 Millimeter --> 1.3E-05 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r = R-(e+h_°) --> 0.026-(1.1E-05+1.3E-05)

Evaluating ... ...

r = 0.025976

STEP 3: Convert Result to Output's Unit

0.025976 Meter -->25.976 Millimeter (Check conversion here)

FINAL ANSWER

25.976 Millimeter <-- Radius of Journal
