MOI_CircularSegmentArc

 

 

This procedure returns the length and center of mass of a half circle arc.

 

Inputs

r = radius of arc [m, ft]

 

Outputs

L = length [m, ft]

x_bar = distance from center of arc to centroid in y-direction [m or ft]

 

Example:  

$Load Mechanical Design

$UnitSystem SI K Pa rad

$VarInfo L units=m

$VarInfo x_bar units=m

r = 0.25 [m]

alpha = 0.3 [rad]

 

Call moi_circularsegmentarc(r, alpha: L, x_bar)

 

 

{Solution:

L = 0.15 [m]

x_bar = 0.2463 [m]

}
