A material's Unwillingness to
be drawn, stretched or formed.
Breaks easily
Answer:
Brittle
Explanation:
A brittle material is one that shows unwillingness to be drawn, stretched or formed. These materials are opposite of ductile ones{copper & aluminum} that can be formed into sheets or drawn into wires. A brittle material is hard but liable to break easily. Example of material include : cast iron, ceramics and concrete.

Vs = 9 V, I = 13.6 mA. What is R?
Answer:
661.7 ohm
Explanation:
The base formula for the solution is
[tex]i = \frac{v}{r} [/tex]
so the I is equal to V divided by R and so we can change the formula according to the given stats so we change it to
[tex]r = \frac{v}{i} [/tex]
just put the stats in V and I and you will get the answer, don forget to change the milliampere to ampere!!

A team of engineers is tasked with designing a hydraulic engine for a motorboat that is as efficient as possible. Identify three of the
seven design phases, and explain why they are individually important in the design process.
Help ASAP!
Answer:
Driving surface area as subject to differential pressuresHow to achieve continuous rotationMechanical connectionsExplanation:
The general stages of thinking when designing a system are;
First understanding the problem that requires you to design a solutionDefining the problem that needs to be solved. In this case is to design an efficient hydraulic engine for a motorboatResearch to find any available solutions for similar problemsIdea of the solutionA prototype to try solve the challengeSelecting and adjusting the prototype as you implement the solution.For a hydraulic engine design, the following designing parts are vital;
Driving surface area as subject to differential pressuresHow to achieve continuous rotationMechanical connectionPressures are important due to motor displacements. Fuel burns in the cylinder to cause power through fuel gases burning and expansion which is the four-stroke cycle. Continuous rotation will come in the design considerations through reciprocating motions of pistons into rotary motions. Mechanical connections are vital especially in crank shaft turns, gear box that turns horizontal motions to spinning motions and finally the propeller that drives the boat on the water.

Explain how an enhanced fluid power system improved efficiency in the following scenario.
Oliver has designed a new dump truck that is emitting 50 percent less carbon and needs 60 percent less fuel to run. The savings will
allow his construction company to purchase two more vehicles.
HELP !!
Answer:
He can go a few places instead doing to many pit stops
Explanation:
Answer:
The correct answer is that the system may be equipped with microstructures to reduce the friction of the fluid.
Explanation:
Oliver may have implemented a regenerative braking system, decreasing the amount of energy lost in the braking process. He also may have eliminated valves. Valves are highly susceptible to wear in a fluid power system. He may have used an actuator instead.
I need to drop 10 V to feed an LED from a 12 V power supply. The resistor value is 490 Ω. How much of my battery power will be wasted in the resistor?
Answer:
P = 0.204 W
Explanation:
Given that,
Voltage drop is 10 V to feed an LED from a 12 V power supply. The resistor value is 490 Ω.
We need to find how much of my battery power will be wasted in the resistor. The power of a battery is given in terms of voltage and resistance is given by :
[tex]P=\dfrac{V^2}{R}[/tex]
V is the voltage drop to feed an LED
Putting all the values,
[tex]P=\dfrac{(10)^2}{490}\\\\P=0.204\ W[/tex]
So, 0.204 W of power will be wasted in the resistor.
Annie has been designing a new pool filter for pools of over 5,000 gallons. The prototype she designed works well, but only on pools of less than 3,000 gallons. Which statement explains why Annie is not frustrated?
A. Engineers still need to design filters for smaller pools; this prototype can be distributed to other clients.
B. Engineers work in a cyclical process; she can just begin a totally new project.
C. Engineers can always take an existing idea and expand on it.
D. Engineers will not allow failures to stop them; a previous failure can be a practical solution for a new problem.
Answer:
C. Engineers can always take an existing idea and expand on it.
Explanation:
Engineers are problem solvers. When they identify a challenge, they design solutions and test the ideas using a prototype. When the prototype performs the desired output, they go ahead to implement a full design. This is to say, they take the existing idea that works in certain parameters and expand it to fit the intended solution.
Answer choices A,B, and D are true but not correct because the issue of frustration is not indicated. They are true because they explain the general form of working of engineers which is: continuing designing everyday to solve new problems, the work done by engineers has stages and processes and finally because engineers seek to give solutions, failure is not failing but a new problem that needs a new idea as a solution.

Section views give a clear indication of interior views of an object or structure including hidden parts or features which are not directly visible through convectional ways such as direct observation.
Which option should the engineers focus on as they develop the train in the following scenario?
Richmond, Virginia, has recently approved the construction of a metro system throughout part of the city. As engineers study other
metro lines, they notice that there is an extreme amount of energy lost as the trains start and stop.
Engineers can design a train with additional valves to increase energy.
O Engineers can design a train with additional fluid pumps to increase efficiency
Engineers can design a train with a regenerative braking system.
Engineers can design a train involving larger hydraulic power systems.
lol
Answer:
Engineers can design a train with a regenerative braking system
Explanation:
Assuming the point of the question is that the engineers want to focus on using energy efficiently when starting and stopping, they would likely want to consider a regenerative braking system. Such a system can store energy during braking so that it can be used during starting, reducing the amount of energy that must be supplied by an outside power source.
