Close up of the weighing and velocity functionality. The motor is indicated to show where a driving force/torque for the velocity mode is put into the mechanism. Here, F and τ denote a force or torque applied to the mechanism by the motor used to move the coil in the velocity mode. Furthermore, φ and ω are the deflection angle and angular velocity of the main pivot. Finally, Δz and v are the translational displacement and velocity of the coil in vertical direction constrained by a guiding mechanism
