Answer:
percent elongation is 54%
reduction area is 73%
Explanation:
original diameter = 0.500 in
gauge length = 2.000 in
diameter of the specimen is 0.260 in
fractured gauge length = 3.08 in
solution
we get here ductility in terms of percent elongation that is express as
elongation = ........1
elongation =
elongation = 0.54
so percent elongation is 54%
and
now we get cross section of this section is
Ao = × 0.5²
Ao = 0.1963 in²
so now calculate final cross section area
A(f) = × 0.26²
A(f) = 0.0530 in²
so percent reduction in area will be
percent reduction area = ..............2
percent reduction area =
percent reduction area = 73%
there is reduction area is 73%
