What is the smallest variable type I can use to represent the number 27?

For the following production environments, indicate whether the preferred production system is more likely to be a job shop (pro

Nina [5.8K]

Answer:

A) Batch shop production

B) Batch shop production

C) Job shop production

D) production line

Explanation:

A)The preferred production system here will be Batch shop production because the manufacturer produces different styles of clothing and sells to small specialty stores hence producing in Batches can help meet up the needs

B) The preferred production system here will be Batch shop production because the manufacturer produces Gaskets and they are of different styles hence he needs to produce them in batches

C) Job shop production

D) production here is streamlined to a particular ( tablet form ) hence the production system here would be a Production line system of production

Suppose that a wing component on an aircraft is fabricated from an aluminum alloy that has a plane-strain fracture toughness of

Orlov [11]

Answer: 133.88 MPa approximately 134 MPa

Explanation:

Given

Plane strains fracture toughness, k = 26 MPa

Stress at which fracture occurs, σ = 112 MPa

Maximum internal crack length, l = 8.6 mm = 8.6*10^-3 m

Critical internal crack length, l' = 6 mm = 6*10^-3 m

We know that

σ = K/(Y.√πa), where

112 MPa = 26 MPa / Y.√[3.142 * 8.6*10^-3)/2]

112 MPa = 26 MPa / Y.√(3.142 * 0.043)

112 = 26 / Y.√1.35*10^-2

112 = 26 / Y * 0.116

Y = 26 / 112 * 0.116

Y = 26 / 13

Y = 2

σ = K/(Y.√πa), using l'instead of l and, using Y as 2

σ = 26 / 2 * [√3.142 * (6*10^-3/2)]

σ = 26 / 2 * √(3.142 *3*10^-3)

σ = 26 / 2 * √0.009426

σ = 26 / 2 * 0.0971

σ = 26 / 0.1942

σ = 133.88 MPa

When implementing a safety and health program, management leadership does not need employee participation a True b) False Effect

sladkih [1.3K]

Answer: I have answered the questions in rephrased sentences as below;

When implementing a safety and health program, management leadership need employee participation. Effective management of worker safety and health programs has improved employee productivity and morale in the workplace.

Nearly a third of all serious occupational injuries and illnesses stem from overexertion of repetitive motion.

Training is a way for employers to provide tools to enable employees to protect themselves and others from injuries.

Under OSHA, employees are protected from discrimination when reporting a work-related injury, illness, or fatality.

Explanation: All personnel including management & employees must be directly involved when workplace HSE policies are being made & reviewed. This is because everyone in the work environment is impacted one way or the other when incidents occur.

Training & Reporting are key responsibilities of managers, employers & supervisors, so it is mandatory to be done without discrimination so as to foster employees happiness which ultimately lead to zero incidents & increased productivity & profit.

Water is the working fluid in an ideal Rankine cycle. Steam enters the turbine at 1400 lbf/in2 and 1000°F. The net power output

Alex17521 [72]

Answer:

(a) The mass flow rate of the steam is approximately 1.803×10⁶ lb/h

(b) The rate of heat transfer is approximately 2.52×10⁹ BTU/h

(c) The thermal efficiency is approximately 39.68%

(d) The mass flow rate of cooling water is approximately 9.478 × 10⁷ lb/h

Explanation:

(a) The parameters are;

T₁ = 1000 F, P₁ = 1400 psi

By using an online application, we have;

h₁ = 1494 BTU/lb = 3,475 kJ/kg

s₁ = 1.61 BTU/(lb·R) = 6.741 kJ/(kg·K)

Therefore, due to isentropic expansion from state 1 to state 2, we have;

s₁ = s₂ = 1.61 BTU/(lb·R)

P₂ = 2 psi

T₂ =

$s_f$ = 0.17498 BTU/(lb·R)

$h_{f2}$ = 94.02 BTU/(lb)

$h_g$ = 1116 BTU/lb

$s_g$ = 1.919 BTU/(lb·R)

We have;

x₂ = (1.61 - 0.17498)/(1.919 - 0.17498) ≈ 0.823

h₂ = $h_f$ + x₂×( $h_g$ -

P₃ = P₂ = 2 psi

h₃ = $h_{f2}$ = 94.02 BTU/(lb)

v₃ = 0.01605 ft³/lb

h₄ = h₃ + v₃ × (P₄ - P₃)

h₄ = 94.02 + 0.01605 × (1400 - 2) ×144/778 = 98.17 BTU/lb

The mass flow rate of the steam, $\dot m$ = $\dot W$ /((h₁ - h₂) - (h₄ - h₃)) = 1 * 10^9/((1494 -935.11) - (98.17 -94.02)) ≈ 1.803×10⁶ lb/h

$\dot m$ ≈ 1.803×10⁶ lb/h

The mass flow rate of the steam ≈ 1.803×10⁶ lb/h

(b)The rate of heat transfer, $\dot Q_{in}$ = $\dot m$ × (h₁ - h₄) = 1.803×10⁶×(1494 -98.17) ≈ 2.52×10⁹ BTU/h

$\dot Q_{in}$ ≈ 2.52×10⁹ BTU/h

(c) The thermal efficiency = $\dot W_{cyc}$ / $\dot Q_{in}$ = 1×10⁹/(2.52×10⁹) = 0.3968 ≈ 39.68%

The thermal efficiency ≈ 39.68%

(d) The mass flow rate of cooling water $\dot m_w$ = $\dot m$ (h₂- h₃)/( $c_w \Delta T$ )

$c_w$ = 1 BTU/(lb·°F)

$\dot m_w$ = 1.803×10⁶ (935.11- 94.02)/(1 * (76 - 60)) ≈ 9.478 × 10⁷ lb/h

$\dot m_w$ ≈ 9.478 × 10⁷ lb/h

The mass flow rate of cooling water ≈ 9.478 × 10⁷ lb/h.

Sections of this interstate have speed limits of 65mph. A construction site is located on this interstate near Boise, ID. In the

e-lub [12.9K]

Answer:

Explanation:

Given Preception time = 1.0 sec

Deceleration rate = 11 ft /sec2

Interpretation rate as = 3words /sec

The board consists of “WORK ZONE: 20 MPH SPEED ZONE”

Then Interpretation time = 2.0 sec

Decision time = 0.5 sec

Assume that the vehicle was traveling with 65mph

Perception Time

So, if you’re driving at 65 mph, your vehicle will travel 71 feet before you realize you need to start braking.

Reaction Distance

At 65 mph, that’s another 71 feet traveled.

Braking Distance

At 65 mph, it takes an additional 5.5 seconds or about 525 feet of actual brake application to stop your vehicle.

Stopping Distance

To determine the stopping distance, you calculate: Perception Distance (71 feet) + Reaction Distance (71 feet) + Braking Distance (525 feet) = Stopping Distance (667 feet)

Then to reduce the speed it takes 7.0 secs
