Circular Section
This procedure returns properties of a circular section.
Inputs
d = diameter [m, ft]
Outputs
A = area [m^2, ft^2]
I = moment of inertia about centroid [m^4, ft^4]
Z = section modulus [m^3, ft^3]
J = polar moment of inertia about centroid [m^4, ft^4]
rho = radius of gyration about centroid [m, ft]
Example:
$UnitSystem SI K Pa
$VarInfo A units=m^2
$VarInfo I units=m^4
$VarInfo J units=m^4
$VarInfo rho units=m
$VarInfo Z units=m^3
d=0.12 [m]
Call moi_circle(d: A, I, Z, J, rho)
{Solution:
A=0.01131 [m^2]
I=0.00001018 [m^4]
J=0.00002036 [m^4]
rho=0.03 [m]
Z=0.0001696 [m^3]
}
