The phrase "at a constant force" is correct and usable in written English.
It can be used in contexts related to physics, engineering, or any discussion involving forces that remain unchanged over time.
Example: "The object was moved at a constant force, ensuring a steady acceleration throughout the experiment."
Alternatives: "under a steady force" or "with a uniform force".
In the second experiment, EMG at a constant force (30% MVGF) was evaluated as a function of the grip span.
A silicon tip is scanned across the surface of a sample at a constant force of 16 N/m.
Using the recently developed single molecule force-clamp technique we quantitatively measure the kinetics of conformational changes of polyprotein molecules at a constant force.
The samples were scanned with a standard Si cantilever at a constant force of 22 N/m and resonance frequency of 325 kHz (10-nm tip radius, 95-μm tip length).
The samples were scanned with the standard Si cantilever at a constant force of 22 N/m and a resonance frequency of 325 kHz (10 nm tip radius, 95 μm tip length).
It is shown that the unfolding of the quaternary structure of the PapA rod takes place at a constant force that is almost independent of elongation speed for slow elongations (up to ∼0.4 μm/s), whereas it shows a dynamic response with a logarithmic dependence for fast elongations.
All experiments were conducted at 3 mM ATP and a constant force of 5 pN.
In this paper the dynamic problem of a simple supported beam subjected to a constant force moving at a constant speed is discussed.
Events were considered a stall and included in the statistical analysis if the motor could hold a constant force for at least 50 ms before releasing from the microtubule.
If this were the only explanation, however, we might expect all animals to operate near a constant force or stiffness limit at all sizes and speeds.
The SNARE complex was then pulled at a uniform trap separation speed or held at an approximately constant force or trap separation.
