Tube and pipe basics: How to achieve the perfect bend

The roller effectively "compresses" the tube against the central bend die. This method is most common in symmetrical workpieces—those with identical bends on either side—often bent in one setup on a machine with two bending heads. This method works well for tubes bent to a CLR that's at least three times the tube OD.

Ring and Pinion Gear Selection for Optimal Performance

The easiest method is to have the axle cover removed and physically count the number of teeth on the ring and pinion gears. Then take the number of ring gear teeth and divide by the number of pinion teeth. A ring gear with 41 teeth that meshes with a pinion that has 10 teeth yields 41 ÷ 10 or 4.10:1 axle ratio.

Spillway - Wikipedia

This design allows nearly the full height of the dam to be used for water storage year-round, and flood waters can be released as required by opening one or more gates. An uncontrolled spillway, in contrast, does not have gates; when the water rises above the lip or crest of the spillway, it begins to be released from the reservoir.
