Each piston has a radius of 45 mm and the cylinder has a wall thickness of 2 mm . Determine the maximum force P that can be exerted on each of the two pistons so that the circumferential stress in the cylinder does not exceed 5 MPa .
Answers
The maximum force P that can be exerted on each of the two pistons, without exceeding a circumferential stress of 5 MPa in the cylinder, is approximately 0.222 kilonewtons. This ensures the structural integrity of the cylinder by keeping the stress within the acceptable limit.
The maximum force P that can be exerted on each of the two pistons, without exceeding a circumferential stress of 5 MPa in the cylinder, can be determined using the principles of stress analysis.
To calculate the maximum force, we need to consider the stress acting on the cylinder wall. The circumferential stress (also known as hoop stress) in a thin-walled cylinder is given by the formula:
σ = P * r / t
Where σ is the circumferential stress, P is the force applied, r is the radius of the cylinder, and t is the wall thickness.
In this case, the radius of the pistons is given as 45 mm and the wall thickness of the cylinder is 2 mm. We need to find the maximum force P. Rearranging the formula, we have:
P = σ * t / r
Substituting the given values, we get:
P = (5 MPa) * (2 mm) / (45 mm)
P = 0.222 kN
Therefore, the maximum force P that can be exerted on each of the two pistons is approximately 0.222 kilonewtons to ensure that the circumferential stress in the cylinder does not exceed 5 MPa.

Deliverables 1. List the PDU at layers 2, 3, and 4 that were used to transmit your HTTP GET packet. 1. Locate your HTTP GET packet in the Packet List and click on it. 2. Look in the Packet Detail window to get the PDU information. 2. How many different HTTP GET packets were sent by your browser? Not all the HTTP packets are GET packets, so you'll have to look through them to answer this question. 3. List at least five other protocols that Wireshark displayed in the Packet List window. You will need to clear the filter by clicking on the "Clear" icon that is on the right of the Filter toolbar
Answers
Answer:
Explanation:
1. The PDU (Protocol Data Unit) at layers 2, 3, and 4 used to transmit an HTTP GET packet are as follows:
- Layer 2: Ethernet II frame (Ethernet PDU)
- Layer 3: Internet Protocol (IP) packet (IP PDU)
- Layer 4: Transmission Control Protocol (TCP) segment (TCP PDU)
To locate the specific PDUs for an HTTP GET packet in Wireshark:
1. Open Wireshark and load the captured packet trace.
2. Find the HTTP GET packet in the Packet List.
3. Click on the HTTP GET packet to select it.
4. In the Packet Detail window, navigate to the "Frame" section to view the Ethernet II frame details (Layer 2).
5. Scroll down to the "Internet Protocol" section to see the IP packet information (Layer 3).
6. Further down, in the "Transmission Control Protocol" section, you will find details about the TCP segment (Layer 4).
2. To determine the number of different HTTP GET packets sent by a browser, inspect the captured packets. Look for packets with the "GET" method in the "Info" column of the Packet List. Counting the unique occurrences of such packets will give you the number of different HTTP GET packets sent by the browser.
3. Five other protocols that Wireshark may display in the Packet List window, after clearing the filter, include:
- DNS (Domain Name System)
- ICMP (Internet Control Message Protocol)
- ARP (Address Resolution Protocol)
- TLS (Transport Layer Security)
- DHCP(Dynamic Host Configuration Protocol)
By reviewing the Packet List window, you can identify and list at least these five additional protocols displayed alongside HTTP.

the failure of engineers working on the mars climate-orbiter to coordinate measurement standards resulted in major public embarrassment for nasa. the years of interaction between british and u.s. teams working on this project are an example of what communication issue?
Answers
Answer: The failure of engineers working on the Mars Climate-Orbiter to coordinate measurement standards, resulting in a major public embarrassment for NASA, is an example of a communication issue known as cultural difference or cross-cultural communication. This refers to the difficulties that can arise when people from different cultures, with different languages, customs, and communication styles, work together on a project. In this case, the interaction between the British and U.S. teams working on the Mars Climate-Orbiter project is an example of cultural differences that led to communication issues and ultimately resulted in the failure of the project.
Specifically, the engineers from the US team used the imperial system of measurement, while the engineers from the UK team used the metric system, this led to a misinterpretation of the data, and the orbiter was lost due to a miscalculation in the trajectory.

Answer: a. 0.4667
b. 0.4667 and C 0.0667
Explanation:
Given Data:
N = population size (10)
n = random selection (2)
r = number of observations = 7
Therefore
f(y) = ( r/y ) ( N - r / n - y ) / ( N /n )
When y = 1
f(1) = ( 7/1 ) ( 10 - 7 / 2 -1 ) / ( 10/2 )
= 7 / 15
= 0.4667
When y = 2
f(2) = ( 7/2 ) ( 10 - 7 / 2 -2 ) / ( 10/2 )
= 7 / 15
= 0.4667
When y = 0
f(0) = ( 7/0 ) ( 10 - 7 / 2 -0) / ( 10/2 )
= 1 / 15
= 0.0667
For every 3 people at the concert singing along, there are 5 people not singing along. If there are 180 more people not singing along, how many total people are at the concert?
Answers
Answer:
The total people are at the concert
= 296
Explanation:
a) Data and Calculations:
Ratio of the number of people singing along at the concert to the number of people not singing along
= 3:5
The number of more people not singing along = 180
Therefore, the total number of people not singing along = 185 (180 +5)
Every person singing along = 185/5 * 3 = 111
Total number of people at the concert = number of people not singing along plus number of people singing along
= 185 + 111
= 296

When E = 14 V and R = 12 Ω, the current is _________ amperes.
Answers
Answer:
When E = 14 V and R = 1 Ω, the current is 14 A.
When E = 14 V and R = 4 Ω, the current is 3.5 A.
When E = 14 V and R = 8 Ω, the current is 1.75 A.
When E = 14 V and R = 12 Ω, the current is 1.166... A
(rounded to three decimal places).
Explanation:
To calculate the current (I) using Ohm's law, we can use the formula:
I = E / R
where I is the current in amperes (A), E is the voltage in volts (V), and R is the resistance in ohms (Ω).
Answer:
Current = Emf / Resistance
When E = 14 V and R = 1 Ω, the current is 14/1 amperes = 14 amp
When E = 14 V and R = 4 Ω, the current is 14/4 amperes = 3.5 amp
When E = 14 V and R = 8 Ω, the current is 14 / 8 amperes = 1.75 amp
When E = 14 V and R = 12 Ω, the current is 14 / 12 amperes = 1.16 amp

A packet-switching scenario withNps users sharing a 150 Mbps link, where each user again requires 25 Mbps when transmitting, but only needs to transmit 10 percent of the time.
What is the probability that a given (specific) user is transmitting, and the remaining users are not transmitting?
Answers
Answer:
0.09
Explanation:
Packet switching involves breaking a message into packets and sending them independently. Since the user only needs to transmit 10 percent of the time, the probability that a given (specific) user is transmitting = 10% = 0.1
The probability that a user is not transmitting = 100% - 10% = 90% = 0.9
Therefore, the probability that a given (specific) user is transmitting, and the remaining users are not transmitting = 0.1 * 0.9 = 0.09

Answers
Answer:
The thickness of the material is 6.23 cm
Explanation:
Given;
quantity of heat, Q = 6706.8 *10⁶ kcal
duration of the heat transfer, t = 5 months
thermal conductivity of copper, k = 385 W/mk
outside temperature of the heater, T₁ = 30° C
inside temperature of the heater, T₂ = 50° C
dimension of the rectangular heater = 450 cm by 384 cm
1 kcal = 1.163000 Watt-hour
6706.8 *10⁶ kcal = 7800008400 watt-hour
I month = 730 hours
5 months = 3650 hours
Rate of heat transfer, P = \(\frac{7800008400 \ Watt-Hour}{3650 \ Hours} = 2136988.6 \ W\)
Rate of heat transfer, \(P = \frac{K*A *\delta T}{L}\)
where;
P is the rate of heat transfer (W)
k si the thermal conductivity (W/mk)
ΔT is change in temperature (K)
A is area of the heater (m²)
L is thickness of the heater (m)
\(P = \frac{KA(T_2-T_1)}{L} \\\\L = \frac{KA(T_2-T_1)}{P}\\\\L = \frac{385(4.5*3.84)(50-30)}{2136988.6}\\\\L = 0.0623 \ m\)
L = 6.23 cm
Therefore, the thickness of the material is 6.23 cm
