A cylindrical metal specimen having an original diameter of 10.48 mm and gauge length of 47.1 mm is pulled in tension until fracture occurs. The diameter at the point of fracture is 7.52 mm, and the fractured gauge length is 69.4 mm. Calculate the ductility in terms of (a) percent reduction in area (percent RA), and (b) percent elongation (percent EL).

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
