Engineering

 * Shear strength (soil), the shear strength of soil under loading
 * Shear line (locksmithing), where the inner cylinder ends and the outer cylinder begins in a cylinder lock
 * Shearing (manufacturing), a metalworking process which cuts stock without the formation of chips or the use of burning or melting
 * Shear (sheet metal), various tools to shear sheet metal
 * Board shear, in bookbinding, a tool to cut board or paper
 * Shear pin, in machinery, such as a plough, designed to shear (break) when a certain force is exceeded, to protect other components of the machine.
