The phrase "axis of force" is correct and usable in written English.
It can be used in contexts discussing dynamics, physics, or metaphorical frameworks where forces are being analyzed or described.
Example: "In the study of mechanics, understanding the axis of force is crucial for predicting the movement of objects."
Alternatives: "line of force" or "vector of force".
In the lateral calibration setup as shown in Figs. 5(a) and 5(b), we maintained the tool shaft (z axis of the force coordinate) perpendicular to the gravity direction so that the force induced by the gravity of the testing weights had only a lateral component in the force coordinate that was attached to the tool tip; in other words, F z = 0.
In order to do this, we attached the tool to a rotary stage in x- y plane to change the angle between the x axis of our force coordinate and the direction of gravity.
As a result, it is more convenient to decomposition F l in x- y plane as F x, F y and afterwards use Eq. (11) to calculate F l, which would be independent of the choice of x or y axis of our force coordinate.
These "axis of resistance" forces would most likely project their formidable military power — which includes chemical weapons in the case of Syria — against their enemies in a fight for their collective existence.
But Asadullah Saburi, Iran's second-highest nuclear official, says this is unlikely until the world drops what he regards as an unjust "embargo .Iran's isolation, which has grown more acute since George Bush included it in his "axis of evil", forces it to rely on Russia for many things.
This view of the world, which turns Bush and Blair into the real "axis of evil", gains force with each indignant repetition.
Strain elastography measures tissue displacements occurring along the axis of an applied force, which are termed longitudinal, bulk or compression waves.
For the measurements discussed in the paper, we focus on the force component along the shearing direction (Fig. 1a) Fapp=Fcosθ, where F is the force along the axial direction and θ is the angle between the axis of the micro-force sensing probe and the shearing direction.
In uniaxial tests, a specimen, usually a rectangular or dumbbell-shaped strip of cuticle or skin, is subjected to a defined force applied along the axis of extension and the force and extension are monitored.
A symmetrical distribution of angles for S2 with respect to the filament axis at the beginning of force production might explain the lack of coupling between axial and azimuthal lever arm angles of strong binding bridges, but it does not explain the strong directional bias (Fig. 4).
