## Allowable Bearing Stress in the Local Zone Solution

STEP 0: Pre-Calculation Summary
Formula Used
allowable_bearing_stress = 0.48*cube strength*sqrt(Bearing Area Between Screw and Nut/Punching area)
Fp = 0.48*fci*sqrt(Ab/Apun)
This formula uses 1 Functions, 3 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
cube strength - cube strength can be describes as the strength of the cube to transfer (Measured in Newton per Square Millimeter)
Bearing Area Between Screw and Nut - Bearing Area Between Screw and Nut is defined as the area of contact of one thread, between one mating pair of Screw and Net. (Measured in Square Millimeter)
Punching area - Punching area can be described as the defined as the space occupied by a flat shape or the surface of an object. (Measured in Square Meter)
STEP 1: Convert Input(s) to Base Unit
cube strength: 50 Newton per Square Millimeter --> 50000000 Pascal (Check conversion here)
Bearing Area Between Screw and Nut: 10 Square Millimeter --> 1E-05 Square Meter (Check conversion here)
Punching area: 50 Square Meter --> 50 Square Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Fp = 0.48*fci*sqrt(Ab/Apun) --> 0.48*50000000*sqrt(1E-05/50)
Evaluating ... ...
Fp = 10733.126291999
STEP 3: Convert Result to Output's Unit
10733.126291999 Pascal -->0.010733126291999 Megapascal (Check conversion here)
0.010733126291999 Megapascal <-- Allowable bearing stress
