Specific weight of the pop,

Density of the pop,

**Given:**

Volume of pop, V = 360 mL = 0.36 L =

Mass of a can of pop , m = 0.369 kg

• Use the reference on "Practical Considerations for Rectangular Reinforced Concrete Beams"

• Include references to ACI code – see slides from second class

• Include references to Tables from Appendix A

• Draw a sketch of the reinforced concrete beam showing all dimensions, number and size of rebars, including stirrups.

Answer:

Beam of 25" depth and 12" width is sufficient.

I've attached a detailed section of the beam.

Explanation:

We are given;

Beam Span; L = 20 ft

Dead load; DL = 0.50 k/ft

Live load; LL = 0.65 k/ft.

Beam width; b = 12 inches

From ACI code, ultimate load is given as;

W_u = 1.2DL + 1.6LL

Thus;

W_u = 1.2(0.5) + 1.6(0.65)

W_u = 1.64 k/ft

Now, ultimate moment is given by the formula;

M_u = (W_u × L²)/8

M_u = (1.64 × 20²)/8

M_u = 82 k-ft

Since span is 20 ft, it's a bit larger than the average span beams, thus, let's try a depth of d = 25 inches.

Effective depth of a beam is given by the formula;

d_eff = d - clear cover - stirrup diameter - ½Main bar diameter

Now, let's adopt the following;

Clear cover = 1.5"

Stirrup diameter = 0.5"

Main bar diameter = 1"

Thus;

d_eff = 25" - 1.5" - 0.5" - ½(1")

d_eff = 22.5"

Now, let's find steel ratio(ρ) ;

ρ = Total A_s/(b × d_eff)

Now, A_s = ½ × area of main diameter bar

Thus, A_s = ½ × π × 1² = 0.785 in²

Let's use Nominal number of 3 bars as our main diameter bars.

Thus, total A_s = 3 × 0.785

Total A_s = 2.355 in²

Hence;

ρ = 2.355/(22.5 × 12)

ρ = 0.008722

Design moment Capacity is given;

M_n = Φ * ρ * Fy * b * d²[1 – (0.59ρfy/fc’)]/12

Φ is 0.9

f’c = 4,000 psi = 4 kpsi

fy = 60,000 psi = 60 kpsi

M_n = 0.9 × 0.008722 × 60 × 12 × 22.5²[1 - (0.59 × 0.008722 × 60/4)]/12

M_n = 220.03 k-ft

Thus: M_n > M_u

Thus, the beam of 25" depth and 12" width is sufficient.

The most **upstream process **with issues would be a good location to start exploring the cause of the **variance**.

A **manufacturing technique** would be a specific procedure for generating a commodity.

Throughout manufacturing, a **six sigma process** has been utilized just to generate a product throughout which **99.99966 percent** among all **possibilities** to produce certain aspects of a part seem to be likely toward being** defect-free**.

Thus the response above is correct.

Answer: The furthest upstream process that has problems.

A process in manufacturing is a particular method used for producing a product.

A six sigma process is used in processing to produce a product that is 99.99966% of all opportunities to produce some feature of a part are statistically expected to be free of defects.

According to the rules of the six sigma process, when there's a defect, the best thing to do is investigate the furthest upstream process that has problems.

**Answer:**

**Given:**

operating temperature of heat engine,

**Solution:**

For a reversible cycle, maximum efficiency, is given by:

Now, on re designing collector, maximum temperature, changes to , so, the new maximum efficiency, is given by:

**Explanation:**

**Step1**

Absolute pressure is the pressure above zero level of the pressure. Absolute pressure is considering atmospheric pressure in it. Absolute pressure is always positive. There is no negative absolute pressure.

The expression for absolute pressure is given as follows:

Here, is absolute pressure, is gauge pressure and is atmospheric pressure.

**Step2**

Gauge pressure is the pressure that measure above atmospheric pressure. It is not considering atmospheric pressure. It can be negative called vacuum or negative gauge pressure. Gauge pressure used to simplify the pressure equation for fluid analysis.

The **safety risks** are **the same** for technicians who work on **hybrid electric vehicles (HEVs) **or** EVs** as those who work on **conventional gasoline vehicles**: False.

**Safety risks** can be defined as an assessment of the **risks** and **occupational hazards** associated with the use, operation or maintenance of an equipment or **automobile vehicle** that is capable of leading to the;

- Harm of a worker (technician).

- Injury of a worker (technician).

- Illness of a worker (technician).

- Death of a worker (technician).

**Hybrid electric vehicles (HEVs) **or** EVs **are typically designed and developed with parts or components that operates through the use of **high voltage****electrical systems** ranging from 100 Volts to 600 Volts. Also, these type of vehicles have an in-built **HEV** batteries which are typically encased in sealed shells so as to mitigate potential hazards to a **technician**.

On the other hand, **conventional gasoline vehicles **are typically designed and developed with parts or components that operates on hydrocarbon such as fuel and motor engine oil. Also, **conventional gasoline vehicles **do not require the use of **high voltage electrical systems** and as such poses less threat to **technicians**, which is in contrast with **hybrid electric vehicles (HEVs) **or** EVs**.

This ultimately implies that, the **safety risks** for **technicians** who work on **hybrid electric vehicles (HEVs) **or** EVs** are different from those who work on **conventional gasoline vehicles **due to **high voltage electrical systems **that are being used in the former.

In conclusion, **technicians** who work on **hybrid electric vehicles (HEVs) **or** EVs** are susceptible (vulnerable) to being electrocuted to death when safety risks are not properly adhered to unlike **technicians** working on **conventional gasoline vehicles.**

**Answer:**

Batteries are safe when handled properly.

**Explanation:**

Just like the battery in your phone, the battery in some variant of an electric car is just as safe. If you puncture/smash just about any common kind of charged battery, it will combust. As long as you don't plan on doing anything extreme with the battery (or messing with high voltage) you should be fine.
