|
Stiffness influence coefficients |
Set the displacements on a particular position to 1 and 0 other displacements forces will give the stiffness coefficients |
|
|
Stiffness flexibility coefficients |
Set the forces one at a time with no force at all other masses. The displacements will give the flexibility influence coefficients |

|
generalised coordinates |
are any set of coordinates q1,q2 or q3 that are independent and equal to the number of degrees of freedom of the system |

|
Lagrange equation |
|
|
|
advantage of Lagrange equation |
can reduce the mathematics involved to solve a complex system Damping added to a system can overcomplicate the Newtonian method |
