Hardness of Material given CSI Solution

STEP 0: Pre-Calculation Summary

Formula Used

Hardness Figure = ((20*Composite Sleeper Index)-Strength Figure)/10
H = ((20*CSI)-S)/10
This formula uses 3 Variables

Variables Used

Hardness Figure - Hardness Figure is a number which is provided for assuming the hardness of both dry and green timber with 12% moisture content used as sleepers.
Composite Sleeper Index - Composite Sleeper Index refers to composite sleeper index, which evolved from a combination of the properties of strength and hardness.
Strength Figure - Strength Figure is a number generally given for the strength o both green and dry timber used for sleepers.

STEP 1: Convert Input(s) to Base Unit

Composite Sleeper Index: 783 --> No Conversion Required
Strength Figure: 1200 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H = ((20*CSI)-S)/10 --> ((20*783)-1200)/10

Evaluating ... ...

H = 1446

STEP 3: Convert Result to Output's Unit

1446 --> No Conversion Required

FINAL ANSWER

1446 <-- Hardness Figure

Hardness of Material given CSI

Go Hardness Figure = ((20*Composite Sleeper Index)-Strength Figure)/10

Composite Sleeper Index

Go Composite Sleeper Index = (Strength Figure+(10*Hardness Figure))/20

General Strength of Material given CSI

Go Strength Figure = (Composite Sleeper Index*20)-10*Hardness Figure

Hardness of Material given CSI Formula

Hardness Figure = ((20*Composite Sleeper Index)-Strength Figure)/10
H = ((20*CSI)-S)/10
