  • Water Wheel PhysicsThe Physics of a Water Wheel

    Torque or the moment arm is quantified by taking the cross product of the force perpendicular to the axis of rotation and the position vector taking the dot product of these gives us the SI units of Nm. To get the magnitude of torque it is also important to take into consideration the angle theta between the force vector and the position vector.
