Torque, Force and Area Flashcards
1
Q
What is the difference between torque and tensor?
A
Torque = Force * Arm (rotational force)
τ_{ij} =Force/ Area (stress tensor)
2
Q
What is torque?
A
The rotational force - often used when we have cylindrical and/or spherical systems
3
Q
Relation between the change in torque and force
A
dT = r * dF : where r is the radius and dF is the change in force
4
Q
Relation between the change in force and area
A
dF = tau_{ij} dA : where tau_{ij} is the stress tensor and dA is the change in area
5
Q
Relation for the change in area
A
dA = r dr dθ
