Description

The Moments about CG due to Forces block computes moments about center of gravity due to forces that are applied at point CP, not at the center of gravity.

Ports

Input

F — Applied forces

3-element vector

Forces applied at point CP, specified as a three-element vector.

Data Types: double

CG — Center of gravity

3-element vector

Center of gravity, specified as three-element vector.

Data Types: double

CP — Application point of forces

3-element vector

Application point of forces, specified as a three-element vector.

Data Types: double | bus

Output

M — Moments at the center of gravity

3-element vector

Moments at the center of gravity in x-axis, y-axis and z-axis, returned as a three-element vector.

Data Types: double

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"aerolibbdyn/Moments about CG  due to Forces"

Example: add_block("aerolibbdyn/Moments about CG due to Forces","myModel/myBlock",MakeNameUnique="on")
