The structural channel is not used as much in construction as symmetrical beams, in part because its bending axis is not centered on the width of the flanges. If a load is applied equally across its top, the beam will tend to twist away from the web. This may not be a weak point or problem for a particular design, but is a factor to be ...

The term misfit stream is often incorrectly used as a synonym for an underfit stream. An underfit stream is a type of misfit stream whose discharge is too small to be correlated with either existing channel characteristics, i.e. meander radius, wavelength and channel width, or valley size. [1] [2]
I-beams are still available in US sizes from many Canadian manufacturers. In Mexico , steel I-beams are called IR and commonly specified using the depth and weight of the beam in metric terms. For example, a "IR250x33" beam is approximately 250 mm (9.8 in) in depth (height of the I-beam from the outer face of one flange to the outer face of the ...

Although no published standard defines the system, it is produced in a series of conventional sizes which allows for compatibility between manufacturers. There is a variation on T-slot profiles known as V-slot rails where V-slot wheels are slotted into the V-shaped channels of the framing for linear motion in a 3D printer or other CNC machine .
Microchannel in microtechnology is a channel with a hydraulic diameter below 1 mm, usually 1–99 μm. [1] Microchannels are used in fluid control (see Microfluidics), heat transfer (see Micro heat exchanger) and cell migration observation. [2]
Bears receiver Keenan Allen said that issues ran deeper than that and went back to the offseason. “Too nice of a guy," Allen said, according to Kalyn Kahler of ESPN, via Dan Wiederer of the ...
