MOI_QuarterCircleArc
This procedure returns the length and center of mass of a quarter circle arc.
Inputs
r = radius of arc [m, ft]
Outputs
L = length [m, ft]
x_bar = distance from center of arc to centroid in x-direction [m or ft]
y_bar = distance from center of arc to centroid in y-direction [m or ft]
Example:
$Load Mechanical Design
$UnitSystem SI K Pa
$VarInfo L units=m
$VarInfo x_bar units=m
$VarInfo y_bar units=m
r = 0.25 [m]
Call moi_quartercirclearc(r: L, x_bar, y_bar)
{Solution:
L = 0.3927 [m]
x_bar = 0.1592 [m]
y_bar = 0.1592 [m]
}
