raketka [301]

Here is the correct question.

A cylindrical part of diameter d is loaded by an axial force p. this causes a stress of P/A, where A= πd²/4. if the load is known with an uncertainty of ±10 percent, the diameter is known within ±5 percent (tolerances), and the stress that causes failure (strength) is known within ±15 percent, determine the minimum design factor that will guarantee that the part will not fail.

Answer:

the minimum design factor that will guarantee that the part will not fail. = 1.434

Explanation:

Looking at the uncertainty; loss of strength must be raised to $\dfrac{1}{0.85}$ due to the stress that causes the failure (strength) is known within ±15% uncertainty.

Looking at the uncertainty; the maximum allowable load must be reduced to $\dfrac{1}{1.1}$ because the load is known with an uncertainty of ±10.

Looking at the uncertainty; the diameter must be raised to $\dfrac{1}{0.95}$ because the diameter is known within an uncertainty of ±5.

The decrease in the maximum allowable stress can be estimated as:

$\sigma' = \dfrac{P'}{A'}$

where,

$\sigma =$ stress

P = load

A = cross-sectional area of the cylinder

∴

$\sigma' = \dfrac{P'}{\dfrac{\pi}{4}(d')^2}$

replacing P' with $\dfrac{1}{1.1}P$ and d' with $\dfrac{1}{0.95}d$ , we have:

$\sigma' = \dfrac{(\dfrac{1}{1.1})\times p }{\dfrac{\pi}{4}(\dfrac{1}{0.95 } d)^2 }$

$\sigma' =\dfrac{P}{\dfrac{\pi}{4}d^2} (\dfrac{\dfrac{1}{1.1} }{(\dfrac{1}{0.95})^2 }) }$

$\sigma' =\sigma \times (\dfrac{\dfrac{1}{1.1} }{(\dfrac{1}{0.95})^2 }) }$

$\sigma' =\sigma \times 0.82045$

$\dfrac{\sigma' }{\sigma } =0.82045$

Thus, the uncertainty in diameter and the load of the allowable stress needs to decrease to 0.82045

Now, the minimum design factor that will ascertain that the part will not fail can be computed as:

$n_d = \dfrac{loss \ of \ function \ parameter }{maximum \ allowable \ parameter}$

where;

the design factor = $n_d$

$n_d =\dfrac{\dfrac{1}{0.85} }{0.82045}$

the design factor $n_d$ = 1.434.

Thus, the minimum design factor that will guarantee that the part will not fail. = 1.434

Both Mia and Mario specialize in producing the item in which they have a comparative advantage. Then they trade one pasta dish f

FrozenT [24]

Answer:

The total gains from trade are <u>4</u> dishes of pasta and <u>4</u> pizzas an hour.

Explanation:

Before specialization, Mia and Mario each produced 4 dishes of pasta and 4 pizzas per hour. After specialization, Mia is able to produce 12 dishes of pasta, and Mario is able to produce 12 pizzas per hour.

After specialization and trade, the total maximum combined output per hour is 12 dishes of pasta and 12 pizzas. Before specialization, the total maximum combined output per hour was 8 dishes of pasta and 8 pizzas. So the net gain of specialization and trade is 4 dishes of pasta and 4 pizzas per hour.

In 2017 Sabrina earned an annual salary of $100,000 as an engineer. In 2018, her income rose to $105,000. The inflation rate in

blagie [28]

Answer:

Change in Nominal income = 5%

Change in real income = 2.9 %

Explanation:

<em>Real income </em><em>is the amount of basket of goods and services that can be actually purchased . It is the nominal income adjusted for inflation.</em>

<em>Real income = (CPi in base base year/ CPI current year) × Nominal income </em>

Real income for Sabrina

= (100/102) × 105,000

= 102,941.1765

<em>Change in real income</em> = (102,941.1765 -100,000)/100,000

= 2.9 %

<em>Change in Nominal income</em> = (105,000-100,000)/100,000

= 5%
