Unit stream power is stream power per unit channel width, and is given by the equation: = where ω is the unit stream power, and b is the width of the channel. Normalizing the stream power by the width of the river allows for a better comparison between rivers of various widths. [5]
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 ...
In everyday conversation, and in informal literature, it is common to see lengths measured in units of objects of which everyone knows the approximate width. Common examples are: Double-decker bus (9.5–11 meters in length) American football field (100 yards in length) Thickness of a human hair (around 80 micrometers)
The weight of a rail per length is an important factor in determining rail strength and hence axleloads and speeds. Weights are measured in pounds per yard (imperial units in Canada, the United Kingdom and United States) and kilograms per metre in mainland Europe and Australia). 1 kg/m = 2.0159 lb/yd.
