One of the mysteries of the English language finally explained.
A unit of force that, acting on a mass of one gram, increases its velocity by one centimetre per second every second along the direction that it acts.
- ‘Under shear stress of 6.5 dyne / cm 2 chondrocytes drifted on the matrix leaving trails of hyaluronan ‘footprints’.’
- ‘Water's surface tension is about 73 dynes / cm.’
- ‘At room temperature and a lateral pressure of a few dynes / cm, DPPC forms gel-like domains with a very characteristic propeller-like shape.’
- ‘These cells were then perfused at a physiologic shear stress of 2.5 dynes / cm 2 and the number of adherent cells per minute was determined.’
- ‘The centimeter-gram-second system quantifies pressure in dynes per square centimeter.’
Late 19th century: from French, from Greek dunamis ‘force, power’.
