Final answer:
The angle that is not commonly used for offsets and kicks is 60°. Standard bend angles like 22.5°, 30°, and 45° are often used, but 60° is not a standard for these purposes. The maximum range for a projectile is achieved at a 45° launch angle.
Step-by-step explanation:
The correct answer to the question concerning common standard angles of bend in offsets and kicks is d. 60°. While 22.5°, 30°, and 45° are frequently used angles for creating bends and offsets in various materials like pipe or conduit, 60° is less common for these purposes. These standard angles help ensure that installations are consistent and can be easily replicated or understood by professionals in the field.
As for the optimal angle of a projectile launch to achieve maximum range, the answer is b. 45°, based on the projectile's launch angle to maximize range. When simple harmonic motion is considered a good model for a pendulum's swing, it's typically for angles up to approximately 15°. An angle of 60° is typically not utilized for offsets and kicks, nor is it the angle at which the perpendicular component of a box's weight on an inclined plane is maximized; that would be 90°.
