How to Calculate Critical Elastic Moment?
Critical Elastic Moment calculator uses Critical elastic moment=((Moment Gradient Factor*pi)/Unbraced Length of the member)*sqrt(((Modulus Of Elasticity*Moment of Inertia about Y-axis*Shear Modulus*Torsional constant)+(Moment of Inertia about Y-axis*Warping Constant*((pi*Modulus Of Elasticity)/(Unbraced Length of the member)^2)))) to calculate the Critical elastic moment, The Critical Elastic Moment is used as the basis for the methods given in design codes for determining the slenderness of a section. The elastic critical moment (Mcr) is similar to the Euler (flexural) buckling of a strut in that it defines a buckling load. Critical elastic moment and is denoted by M_{cr} symbol.
How to calculate Critical Elastic Moment using this online calculator? To use this online calculator for Critical Elastic Moment, enter Moment Gradient Factor (C_{b}), Unbraced Length of the member (L), Modulus Of Elasticity (E), Moment of Inertia about Y-axis (I_{y)}, Shear Modulus (G), Torsional constant (J) and Warping Constant (C_{w)} and hit the calculate button. Here is how the Critical Elastic Moment calculation can be explained with given input values -> 1.111E+7 = ((1*pi)/0.1)*sqrt(((10000*50*25000000000*10)+(50*10*((pi*10000)/(0.1)^2)))).
