Constant Depending on Material of Column According to Johnson's Parabolic Formula Solution

Follow our step by step solution on how to calculate Constant Depending on Material of Column According to Johnson's Parabolic Formula?

FIRST Step Consider the formula

r = \frac{σ c - (\frac{P}{A sectional})}{\frac{L eff}{r least}}

Next Step Substitute values of Variables

∴

r = \frac{420N/m² - (\frac{5N}{1.4m²})}{\frac{3000mm}{47.02mm}}

Next Step Convert Units

∴

r = \frac{420Pa - (\frac{5N}{1.4m²})}{\frac{3m}{0.047m}}

Next Step Prepare to Evaluate

∴

r = \frac{420 - (\frac{5}{1.4})}{\frac{3}{0.047}}

Next Step Evaluate

∴

r = 6.52682380952381

LAST Step Rounding Answer

∴

r = 6.5268
