massprop_neck {AvInertia} | R Documentation |
Calculate the moment of inertia of a neck modeled as a solid cylinder
massprop_neck(m, r, l, start, end)
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. |
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.
Parallel axis theorem does not apply between two arbitrary points. One point must be the object's center of gravity.
