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%
Answer:
Both Technician A and Technician B are correct
Explanation:
Air tools and electric tools are both power tools as they are used to make work easier. Air tools generally use an air compressor that powers the motor of the tool making it possible to use it while electric tools as the name implies are powered by an electric source which in this case is batteries. An example of an air tool is the nail gun which can be used by furniture makers to drive nails and they are often louder than electric tools because of vibrations caused by the compressor making it necessary to use ear protection when using the tool for ear safety.
Technician B is also correct because it is always advisable to use impact sockets while using impact guns due to the ability of the impact sockets to withstand the force caused by operating impact guns and make work neater when nuts and bolts are being loosened or tightened.
Answer:
$958.25
Explanation:
PV = FV(1 +r)^(-t) . . . . present value of an amount earning rate r compounded annually for t years
PV = $3000(1.08^-5) ≈ $2041.75
The equivalent present value is $2041.75.
__
This amount is less than the offered amount by ...
$3000 -2041.75 = $958.25
She should pay you $958.25 less in order to make the offers equivalent.
