The phrase "angle of the primary" is correct and usable in written English.
It can be used in contexts related to geometry, physics, or any field where angles and primary elements are discussed.
Example: "To determine the trajectory of the projectile, we need to calculate the angle of the primary relative to the horizontal plane."
Alternatives: "primary angle" or "angle of the main".
Open image in new window Fig. 12 The angle of the primary shear crack under various shear-span to depth ratios.
Parameters of interest in this study included the angle of the primary fuel injectors, the distribution of fuel throughout the combustor, and the fuel composition.
Based on the experimental results in Fig. 12, the angle of the primary shear crack is regressed as Eq. (22), which is required to estimate the shear deformation of each specimen.
Thus, the gravitational set-point angle of the primary and lateral roots prior to encountering the barrier were 95° and 136° respectively and after growing off the end of the obstacle identical set-point angles were reinstated.
For this purpose the CMS instrument has been equipped by several newly developed features, among which figures a sample stage and adapted collection optics allowing variations of the impact angle of the primary beam on the specimen at a constant primary energy.
The preoperative Cobb angle of the primary curve and if important for the surgical decision, the Cobb angle of any kyphosis was reported.
Apart from the angle of twist, the primary angle of twist per unit length is considered as an additional 1-D degree of freedom in order to account for the STSDE in the equations of motion of the bar.
The intensity of three reflections from each material was measured for incidence angles of the primary beam ranging from 0.5 to 35°.
The amount of secondary emission depends on the properties of the material and the energy and angle of incidence of the primary electrons.
As Dunbrack and co-workers have shown, the backbone dihedral angles are predictive of the primary χ1 rotamer sampled by side chains.
The information on integral multiplicities of secondary neutrons detected by the neutron monitor in dependence of the zenith angle of incoming primary cosmic ray particles have also been used.
