Slight increase in tool life, since the cutting is partly being done by the built up edge rather than the tool itself. [4] However, the formation of BUEs have negative effects on the quality of the workpiece, [1] specifically: Excessive work hardening at the surface of the workpiece. [1]
Decrease in rag fibre quality may be a culprit; as demand for paper rose in later centuries, papermakers used less water and spent less time cleansing the rag fibres used to make paper. [4] An early work of art to have been affected by foxing is the Portrait of a Man in Red Chalk , a drawing on paper by Leonardo da Vinci .
Notably, "paper" cuts can also be caused by thin, stiff, and abrasive materials other than paper. Paper cuts can be highly painful, even though they may bleed very little, if at all. Although a loose sheet of paper is usually too soft to cut the skin, it can be very thin (sometimes as thin as a razor 's edge), and can thus exert enough pressure ...
Incidental X-ray findings of bone spurs at the adjacent acromioclavicular joint may show a bone spur growing from the outer edge of the clavicle downward toward the rotator cuff. Spurs may also be seen on the underside of the acromion, once thought to cause direct fraying of the rotator cuff from contact friction, a concept currently regarded ...
The motor would not be able to start in this position. However, once it was started, it would continue to rotate through this position by momentum. There is a second problem with this simple pole design. At the zero-torque position, both commutator brushes are touching (bridging) both commutator plates, resulting in a short circuit.
