 #### Formulae required for column type load cell:
 - Cross sectional area = π × r²  where π = 3.14.
-- Axial Strain εa = P / (A×E) = &epsilon;<sub>1</sub> = &epsilon;<sub>3</sub> where, P = Applied load, A = area and E = Young's Modulus.  
-- Transverse Strain εt = (-P × ν) / (A×E) = &epsilon;<sub>2</sub> = &epsilon;<sub>4</sub> where, ν = Poisson's Ratio
