  2. List of motion picture film formats - Wikipedia

    en.wikipedia.org/wiki/List_of_motion_picture...

    Gate dimensions are the width and height of the camera gate aperture, and by extension the film negative frame. Negative pulldown describes the film perforations per frame, the direction of film transport, and standard frame speed. Film transport is assumed to be vertical unless otherwise noted, and standard frame speed is assumed to be 24 ...

  3. Canon EOS 250D - Wikipedia

    en.wikipedia.org/wiki/Canon_EOS_250D

    Techradar labels the EOS 250D as an "entry-level all-rounder" and "one of the best entry-level DSLR cameras you can buy". [5] Digital Camera World states that it's "the best for beginners" and describes the features of the camera as "a combination of point-and-shoot simplicity, a Guided UI (user interface) to walk new users through the basics of photography, and a Creative Assist mode for more ...

    en.wikipedia.org/wiki/Exploded-view_drawing

    An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.

  5. Axes conventions - Wikipedia

    Normally the frames used to describe a vehicle's local observations are the same frames used to describe its attitude with respect to the ground tracking stations. i.e. if an ENU frame is used in a tracking station, also ENU frames are used onboard and these frames are also used to refer local observations.

  6. Problem frames approach - Wikipedia

    en.wikipedia.org/wiki/Problem_Frames_Approach

    Each problem frame has its own frame diagram. A frame diagram looks essentially like a problem diagram, but instead of showing specific domains and requirements, it shows types of domains and types of requirements; domains have general, rather than specific, names; and rectangles representing domains are annotated to indicate the type (causal ...

  7. Shear and moment diagram - Wikipedia

    en.wikipedia.org/wiki/Shear_and_moment_diagram

    Shear and Bending moment diagram for a simply supported beam with a concentrated load at mid-span. Shear force and bending moment diagrams are analytical tools used in conjunction with structural analysis to help perform structural design by determining the value of shear forces and bending moments at a given point of a structural element such as a beam.

  8. Campbell diagram - Wikipedia

    Campbell Diagram of a steam turbine. Analysis shows that there are well-damped critical speed at lower speed range. Analysis shows that there are well-damped critical speed at lower speed range. Another critical speed at mode 4 is observed at 7810 rpm (130 Hz) in dangerous vicinity of nominal shaft speed, but it has 30% damping - enough to ...

  9. System context diagram - Wikipedia

    en.wikipedia.org/wiki/System_context_diagram

    Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram.
