solution:

$sum fx=0\\
n=\frac{1}{2}\times\frac{w_{0}}{a}(2a-x)^2\\
n=\frac{w_{0}}{20}(2a-x)^2\\
angle is the normal shus\\
\sigma =\frac{N}{A}\\
\frac{\frac{w_{0}}{2a}(2a-x)^2}{A}\\
\sigma(x)=\frac{w_{0}}{2aA}[2a-x]^2$

t requires1200 kg of coal to produce the energy needed to make 1.0 kg of aluminum metal. If a single soda can requires approxima

Lesechka [4]

Answer:

The mass of coal is 108 kg.

Explanation:

Given that,

Energy of coal = 1200 kg

Mass of aluminum = 1.0 kg

Energy required for single soda can = 15 g of Al

Energy required for 6 pack of cans = $6\times15=90\ g\ of\ Al$

We need to calculate the mass of coal

Using formula of mass

$\text{mass of coal}=\dfrac{\text{Energy of coal}\times\text{Energy required for 6 pack of cans}}{\text{Mass of aluminum}}$

Put the value into the formula

$m=\dfrac{1200\times90\times10^{-3}}{1.0}$

Put the value into the formula

$m=108\ Kg$

Hence, The mass of coal is 108 kg.

Butoxors [25]

Tolerance enables the engineer to be informed when somethings requires replacement or if there is a drawback with too much war.

The three types of tolerances that appear on dimensioned drawings are limit, bilateral, and unilateral.

<span>General tolerances are normally found in the information blocks of the blueprint while a specific tolerance is noted for certain areas of the blueprint.</span>
