Variables Used
Theoretical Maximum Stress - (Measured in Pascal) - The Theoretical Maximum Stress is when a material will fail or yield when its maximum stress equals or exceeds the shear stress value at the yield point in the uniaxial tensile test.
Stress at any Point y - (Measured in Pascal) - Stress at any Point y is unit stress S, at any point y where y is positive for points on the same side of center of gravity.
Coefficient for Column End Conditions - Coefficient for Column End Conditions is defined as the multiplicative factor for different column end conditions.
Modulus of Elasticity - (Measured in Pascal) - The Modulus of Elasticity is the measure of the stiffness of a material. It is the slope of stress and strain diagram up to the limit of proportionality.
Effective Length of Column - (Measured in Meter) - The Effective Length of Column can be defined as the length of an equivalent pin-ended column having the same load-carrying capacity as the member under consideration.
Radius of Gyration of Column - (Measured in Meter) - The Radius of Gyration of Column about the axis of rotation is defined as the radial distance to a point which would have a moment of inertia the same as the body's actual distribution of mass.
STEP 1: Convert Input(s) to Base Unit
Stress at any Point y: 35000 Pascal --> 35000 Pascal No Conversion Required
Coefficient for Column End Conditions: 2 --> No Conversion Required
