Plate Length Solution

Follow our step by step solution on how to calculate Plate Length?

FIRST Step Consider the formula
N=A1+(0.5((0.95d)-(0.80B)))
Next Step Substitute values of Variables
N=23980mm²+(0.5((0.95140mm)-(0.80150mm)))
Next Step Convert Units
N=0.024+(0.5((0.950.14m)-(0.800.15m)))
Next Step Prepare to Evaluate
N=0.024+(0.5((0.950.14)-(0.800.15)))
Next Step Evaluate
N=0.161354770672395m
Next Step Convert to Output's Unit
N=161.354770672395mm
LAST Step Rounding Answer
N=161.3548mm

How to Evaluate Plate Length?

Plate Length evaluator uses Bearing or Plate Length = sqrt(Area required by Bearing Plate)+(0.5*((0.95*Column Depth)-(0.80*Width of Plate))) to evaluate the Bearing or Plate Length, The Plate Length formula is defined as the minimum length of the plate required to keep an economical design for the base plate. Bearing or Plate Length is denoted by N symbol.

How to evaluate Plate Length using this online evaluator? To use this online evaluator for Plate Length, enter Area required by Bearing Plate (A1), Column Depth (d) & Width of Plate (B) and hit the calculate button.

FAQs on Plate Length

What is the formula to find Plate Length?
The formula of Plate Length is expressed as Bearing or Plate Length = sqrt(Area required by Bearing Plate)+(0.5*((0.95*Column Depth)-(0.80*Width of Plate))). Here is an example- 194604.8 = sqrt(0.02398)+(0.5*((0.95*0.14)-(0.80*0.15))).
How to calculate Plate Length?
With Area required by Bearing Plate (A1), Column Depth (d) & Width of Plate (B) we can find Plate Length using the formula - Bearing or Plate Length = sqrt(Area required by Bearing Plate)+(0.5*((0.95*Column Depth)-(0.80*Width of Plate))). This formula also uses Square Root (sqrt) function(s).
Can the Plate Length be negative?
No, the Plate Length, measured in Length cannot be negative.
Which unit is used to measure Plate Length?
Plate Length is usually measured using the Millimeter[mm] for Length. Meter[mm], Kilometer[mm], Decimeter[mm] are the few other units in which Plate Length can be measured.
