WebApr 11, 2024 · A flank angle of a symmetrical thread is commonly termed the half-angle of thread. Flank Diametral Displacement : In a boundary profile defined system, flank diametral displacement is twice the radial distance between the straight thread flank segments of the maximum and minimum boundary profiles. WebStraight angle: It is one-half of a whole turn, and is the same as the angle made by rays going in opposite directions. The measure of the angle is 180º. Some examples are shown below: Right angle: It is one-quarter of a whole turn and is the same as the angle made by a horizontal line and vertical line. The measure of the angle is 90º. WebThe trigonometric power reduction identities allow us to rewrite expressions involving trigonometric terms with trigonometric terms of smaller powers. This becomes important in several applications such as integrating powers of trigonometric expressions in calculus.

The perimeter of the base of a cone is called the "directrix", and each of the line segments between the directrix and apex is a "generatrix" or "generating line" of the lateral surface. (For the connection between this sense of the term "directrix" and the directrix of a conic section, see Dandelin spheres.) The "base radius" of a circular cone is the radius of its base; often this is simpl… WebField of view is the area of the inspection captured on the camera’s imager. The size of the field of view and the size of the camera’s imager directly affect the image resolution (one determining factor in accuracy). Working distance is the distance between the back of the lens and the target object.
