Resultant Reaction at Journal of Bearing 2 - (Measured in Newton) - Resultant reaction at journal of bearing 2 is the resultant of the horizontal & vertical reaction forces on the 2nd bearing of the crankshaft.
Length of Journal at Bearing 2 - (Measured in Meter) - Length of journal at bearing 2 is the length of the journal at the 2nd bearing of the crankshaft.
Bearing Pressure of Journal at Bearing 2 - (Measured in Pascal) - Bearing pressure of journal at bearing 2 is the compressive stress acting on the contact area between the journal and the crankshaft.

STEP 1: Convert Input(s) to Base Unit

Resultant Reaction at Journal of Bearing 2: 12000 Newton --> 12000 Newton No Conversion Required
Length of Journal at Bearing 2: 48 Millimeter --> 0.048 Meter (Check conversion here)
Bearing Pressure of Journal at Bearing 2: 5 Newton per Square Millimeter --> 5000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_s1 = R₂/(l₂*P_b) --> 12000/(0.048*5000000)

Evaluating ... ...

d_s1 = 0.05

STEP 3: Convert Result to Output's Unit

0.05 Meter -->50 Millimeter (Check conversion here)

FINAL ANSWER

50 Millimeter <-- Diameter of Journal at Bearing 2

(Calculation completed in 00.004 seconds)

What is Journal Bearing?

These are also known as Sliding Bearing. It consists of a journal that rotates inside a bearing. Here journal refers to the shaft. The part of the shaft which rotates inside the bearing is known as journal. It is very simple in construction with no rolling surfaces. The journal slides over the bearing surface and therefore it is also known as Plain bearing for being very simple construction-wise.
Type of Journal Bearings-
1. Hydrodynamic Lubrication
2. Hydrostatic Lubrication
3. Thin Film Lubrication
4. Dry Lubrication / No film Lubrication

Plain Bearing Uses

Journal or Plain bearings are the most widely used types of Hydrodynamic Bearings. They are used in:
Supporting a rotating shaft.
Supporting crankshaft.
Supporting Camshafts.
Used in rocker shaft of rocker arm valve train systems.
