MOI_Ibeam
This procedure returns properties of an I-beam.
Inputs
h = height [m, ft]
b = width [m, ft]
n = height of removed section [m, ft]
t = thickness of web [m, ft]
Outputs
A = area [m^2, ft^2]
I = moment of inertia [m^4, ft^4]
Z = section modulus [m^3, ft^3]
rho = radius of gyration [m, ft]
y_bar = distance from bottom of beam to neutral axis [m, ft]
Example:
$Load Mechanical Design
$UnitSystem SI K Pa
$VarInfo A units=m^2
$VarInfo I units=m^4
$VarInfo rho units=m
$VarInfo Z units=m^3
$VarInfo y_bar units=m
h=0.15 [m]
b=0.15 [m]
n=0.125 [m]
t=0.0125 [m]
Call moi_ibeam(h,b,n,t: A, I, Z, rho, y_bar)
{Solution:
A=0.005313 [m^2]
I=0.00001981 [m^4]
rho=0.06106 [m]
y_bar=0.075 [m]
Z=0.0002641 [m^3]
