2 answers:

3 0

Machining is a process in which a metal is cut into a desired final shape and size by a controlled material-removal process. Machining is a part of the manufacture of many metal products, but it can also be used on materials such as wood, plastic, ceramic, and composites.

What Happens If A Sonic Boom Is Created?

Volgvan

Answer:

Explanation:

A sonic boom is a loud sound kind of like an explosion. It's caused by shock waves created by any object that travels through the air faster than the speed of sound. Sonic booms create huge amounts of sound energy. When an object moves through the air, it makes pressure waves in front of and behind it.

A 350 gal air storage tank is initially at 100 psig. For how long can the tank supply 30 cfm of air to a machine that requires a

devlian [24]

Answer:

93.8 sec

Explanation:

it is given that tab has 350 gallon

we know that 1 gallon = 0.134 cubic foot

350 gallon = 350×0.134=46.9 cubic foot

the delivery pressure is 100 psi which is greater than 80 psi to operate machine

it is given that supply volume is 30 cubic foot per minute

= $\frac{30}{60}=0.5$ $ft^{3}/sec$

$time\ required\ =\frac{tab\ air }{supply\ volume}$

$time\ required\= [tex]\frac{46.9}{0.5}$

=93.8 sec

Social responsibility is an obligation every person has to do to uphold a balance among the economy as well as the environment. Social responsibility refers to maintain the balance between the environment and the budget.

It affects not only corporate governments but also everybody whose activity impacts the climate.

The Social responsibility towards the environment are as follows

1)Defend the environment, create balanced use of natural ingredients, and take important steps to stop pollution from the several processes adopted by the industries.

2)Encourage the viable use of raw resources and natural materials. Introduce strategies for continuously enlightening our environmental duty.

Introduce rules for continuous development in their ecological performance.

Obey with the law in force on conservational protection, and with other willingly recognized promises.

3)To encourage, by on-the-job practice, the participation of all our workers, independently and based on the team, in environmental safety problems.

4)To unite with the liable Agencies as well as Governmental Authorities.

To proceed with environmental protection courses.

5)To talk and report on our eco-friendly management struggles.

Implement and sustain the necessities of a Chain of Custody.

6)Stop trade and acquisition of illegally obtained wood.

7)Apply and continue a due industry system to avoid the acquisition and sale of criminally harvested timber and its products.

An engineer must design a rectangular box that has a volume of 9 m3 and that has a bottom whose length is twice its width. What

Jet001 [13]

Answer:

$Length =3$ $Height = 2$ and $Width = \frac{3}{2}$

Explanation:

Given

$Volume = 9m^3$

Represent the height as h, the length as l and the width as w.

From the question:

$Length = 2 * Width$

$l = 2w$

Volume of a box is calculated as:

$V = l*w*h$

This gives:

$V = 2w *w*h$

$V = 2w^2h$

Substitute 9 for V

$9 = 2w^2h$

Make h the subject:

$h = \frac{9}{2w^2}$

The surface area is calculated as:

$A = 2(lw + lh + hw)$

Recall that: $l = 2w$

$A = 2(2w*w + 2w*h + hw)$

$A = 2(2w^2 + 2wh + hw)$

$A = 2(2w^2 + 3wh)$

$A = 4w^2 + 6wh$

Recall that: $h = \frac{9}{2w^2}$

So:

$A = 4w^2 + 6w * \frac{9}{2w^2}$

$A = 4w^2 + 6* \frac{9}{2w}$

$A = 4w^2 + \frac{6* 9}{2w}$

$A = 4w^2 + \frac{3* 9}{w}$

$A = 4w^2 + \frac{27}{w}$

To minimize the surface area, we have to differentiate with respect to w

$A' = 8w - 27w^{-2}$

Set A' to 0

$0 = 8w - 27w^{-2}$

Add $27w^{-2}$ to both sides

$27w^{-2} = 8w$

Multiply both sides by $w^2$

$27w^{-2}*w^2 = 8w*w^2$

$27 = 8w^3$

Make $w^3$ the subject

$w^3 = \frac{27}{8}$

Solve for w

$w = \sqrt[3]{\frac{27}{8}}$

$w = \frac{3}{2}$

Recall that : $h = \frac{9}{2w^2}$ and $l = 2w$

$h = \frac{9}{2 * \frac{3}{2}^2}$

$h = \frac{9}{2 * \frac{9}{4}}$

$h = \frac{9}{\frac{9}{2}}$

$h = 9/\frac{9}{2}$

$h = 9*\frac{2}{9}$

$h= 2$

$l = 2w$

$l = 2 * \frac{3}{2}$

$l = 3$

Hence, the dimension that minimizes the surface area is:

$Length =3$ $Height = 2$ and $Width = \frac{3}{2}$
