The phrase "angle of the main" is not a standard expression in written English and may be unclear without context.
It could potentially be used in a specific context related to navigation, geometry, or a particular field, but it is not commonly recognized.
Example: "The angle of the main sail needs to be adjusted for optimal performance."
Alternatives: "main angle" or "angle of the primary".
The above mentioned problem is related to two parameters: the angle of the main compression stresses and that of the inclined links.
The actuators of the air path and the crank angle of the main injection are optimised such that the emissions follow a desired trajectory.
The collective pitch control is usually found at the pilot's left hand; it is a lever that moves up and down to change the pitch angle of the main rotor blades.
This study aimed to determine the true inclination angle of the main bronchi relative to the median sagittal plane, using CT imaging to help increase accuracy of double-lumen tube (DLT) placement.
The attitude angle of the main crawler increases.
However, the tilt angle of the main loop structures may be in the range between 10° and 31°.
This paper presents a study of the influence of tool rake angle on the main cutting force for machining rotational parts by sharp cutting tools.
Therefore, the comparative analysis of Cm and Cp, shows that a larger angle of the main-panel can reduce the stability of single-slotted otter-board.
However, when the angle of attack was smaller (0 < α < 22.5°), the lift coefficient of the otter-board increased as the angle of the main-panel increased.
The maximum Cy/Cx of the otter-board with a main-panel angle of 12° was highest (7.417 at α = 2.5°), and the lift drag ratio increased when the angle of the main-panel increased within the angle of attack at small angles (0 < α < 12.5°).
They contain evidence of crossbedding that is, of stratification at an angle to the main plane of sedimentation.
