Basic Question

(OP)
Hi

I have a basic question

I was trying to calculate the torque axis at the rear suspension for an AWD, the way I understand it is the resultant  of the driveshaft torque axis and the halfshaft torque axis , now if I consider them as 2 3D vectors having different origins , and I want to calculate the resultant torque axis , how can I do that

I mean I am trying to understand the math behind it

Thanks for your help

RE: Basic Question

How do you normally add vectors?


Additional very big clue, it doesn't matter where on a rigid body you apply a pure torque.

RE: Basic Question

I know enough to know you give good info, and I don't understand this. Intuitivly it seems like it should matter where your force is as it changes the distance the force is acting over making it a different length lever arm, Or are all forces on a rigid body acting on the center of force for that body?

RE: Basic Question

Yes, the point of application of a torque to a rigid body makes no difference to the resulting acceleration, or force balance.

It is an odd result intuitively, largely because in the real world we usually apply a pair of forces to get a torque, rather than a pure torque.
