0 the force needed to stretch or press a spring, divided by the distance that the spring gets longer or shorter
1 the force needed to to stretch or press a spring, divided by the distance that the spring gets longer or shorter
For this experiment, first the spring constant, k, is determined and then the spring is attached to the bottom of the finger.
Harper et al.17 proposed the design of optimal spring constant to actuate the oscillating foil.
To measure the unknown force, the spring constant of the torsion fiber must first be known.
In these simulations, the spring constant increased at a given rate, thus forcing the biotin out of the streptavidin binding pocket.
The material constants k and are the elastic spring constant and the viscous damping coefficient, respectively.
Another important parameter is the hub tilt spring constant, which influences coupling between the rotor and fuselage.
However, it must be noted that when the piston approaches the mid of the stroke, the equivalent spring constant has a minimum value.
The 'spring constant', whose sign determines stability or instability in the system, incorporates the interfacial area changes and is identical in cases (ii) and (iii).
