massprop_neck: Neck mass properties

In AvInertia: Calculate the Inertial Properties of a Flying Bird

Neck mass properties

Description

Calculate the moment of inertia of a neck modeled as a solid cylinder

Usage

massprop_neck(m, r, l, start, end)

Arguments

m	Mass of muscle (kg).
r	Radius of the neck (m).
l	Length of the stretched neck (m).
start	a 1x3 vector (x,y,z) representing the 3D point where neck starts. Frame of reference: VRP | Origin: VRP.
end	a 1x3 vector (x,y,z) representing the 3D point where neck ends. Frame of reference: VRP | Origin: VRP.

Value

This function returns a list that includes:

• Ia 3x3 matrix representing the moment of inertia tensor of a neck modeled as a solid cylinder.

• CGa 1x3 vector representing the center of gravity position of a neck modeled as a solid cylinder.

• ma double that returns the neck mass.

Warning

Parallel axis theorem does not apply between two arbitrary points. One point must be the object's center of gravity.
