Computer-aided design – (CAD) the use of computer systems (or workstations) to aid in the creation, modification, analysis, or optimization of a design. [46] CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing ...
Definition of the part via a 3D CAD model rather than via a 2D engineering drawing. Drawings may be printed (plotted) from the model for reference use, but the model remains the governing legal instrument. MBP: measurement between pins: threads, splines, gears (internal, female) (synonymous with MBW) (see also MOP, MOW) MBW: measurement between ...
Design variables can be continuous (such as a wing span), discrete (such as the number of ribs in a wing), or Boolean (such as whether to build a monoplane or a biplane). Design problems with continuous variables are normally solved more easily. Design variables are often bounded, that is, they often have maximum and minimum values.
In engineering terms, three-point attachment is the simplest and the only statically determinate way of rigidly joining two bodies. A three-point hitch attaches the implement to the tractor so that the orientation of the implement is fixed with respect to the tractor and the arm position of the hitch.
Bolt preload can also be controlled by torquing the bolt to the point of yielding. Under some circumstances, a skilled operator can feel the drop off of the work required to turn the torque wrench as the material of the bolt begins to yield. At that point the bolt has a preload determined by the bolt area and the yield strength of the bolt ...
If that famous "Final Destination" logging truck scene already lurks in the back of your mind whenever you're driving on a highway, you may want to sit this one out.
The tattooed corpse of a woman was found bizarrely stuffed in a refrigerator dumped in some New Jersey woods — and cops say they need the public’s help identifying her.
The attachment bolt holes (4) are visible around the inboard flange, and indexing pins protrude to ensure that the seals compress uniformly as it is bolted into place. [ 6 ] [ 108 ] Seen here in early 2000, the Z1 PCBM ring (1) is attached to the dome by 96 1/4-inch bolts inside and outside.
