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:
c) Strain
Explanation:
For example, the shear strain “γ” on the surface of the rod is determined by measuring the relative angle of twist “φg” over a gage length “Lg”.
The true statement about the dot plot is 1 has 4 and 0 dots.
Explanation:
- after creating a Bar chart 4 is the right answer.
- The highest among st all the other plots is 1 but 4 shows 3.
- Taking an average from all the data points 3 comes to the right answer.
- Median the central Mid-point is 3.
- Mode also comes to 3.
- It is skewed on the right due to the 1st one.
- Skewed shows the data point either increasing or in decreasing.
- There a to Bi- histograms which has two ups and downs.
- The true statement has to be as Mean=Median=Mode is 3.
Answer:
A retaining of a wall is a protective structure, first and foremost.
Explanation:
Its main aim is to provide functional support for keeping soil in place. It acts as a wall to keep the soil on one side and the rest of the landscape area on the other, providing a platform for a garden to be created.
