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.

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.
Answer:
Engineers can design a train with a regenerative braking system

what is the main job of a cylinder head
Answer: The function of cylinder head is to seal cylinder, form combustion space with piston, and bear the action of high temperature and high pressure gas. The cylinder head bears the mechanical load caused by the gas force and fastening the cylinder bolt, and also bears the high heat load because of the contact with the high temperature gas.
The main function of a cylinder head is to control airflow in and out of the cylinders, as well as fuel deployment.
The cylinder head is the part of an internal combustion engine that sits above the cylinders on the top of a cylinder block.The combustion gas, coolant and lubricating oil can flow freely in the cylinder head.The cylinder head is composed of the valvetrain housing, the head cover, and the combustion chamber.In conclusion, the main function of a cylinder head is to control airflow in and out of the cylinders, as well as fuel deployment.

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.

The status of which of these determines the sequence in which output devices, such as solenoid values and motor contactors, are turned on and off?
A: Physical inputs and outputs
B: NO contract instructions
C: Output coil instructions
The status of physical inputs and outputs determines the sequence in which output devices, such as solenoid values and motor contactors, are turned on and off. The correct option is A.
What is output device?An output device is any piece of computer hardware that transforms data into a form that can be understood by humans or, historically, into a form that can be physically read by machines and used with other non-computerized equipment.
Text, graphics, sound, touch, or video are all acceptable. The primary output component of a computer is the monitor.
An output device enables the computer to convey data in a format that is understandable to humans, such as sound played through a speaker.
The order in which output devices, such as solenoid values and motor contactors, are turned on and off depends on the status of the physical inputs and outputs.
Thus, the correct option is A.

A guitarist would use a tuner to change which element of music?
A guitarist would use a tuner to change "pitch" of music.
An instrument having a lengthy fretting neck that is flat-bodying and generally plays strings (6) with a selection as well as fingertip, is considered as a Guitar.
An electrical gadget that receives or carries the data (signal) as well as enables consumers to observe or monitor TV, would be considered a Pitch. A sound's pitch affects the amount whereas sound intensity depending on the acoustic wave's magnitude.Bass tuners were indeed particularly designed for electric guitars as well as other string instruments, however, guitar tuners routinely operate for guitars along with the basses music.Thus the above is the right answer.
