Answers

Answer 1
1)Disconnect completely meaning that the electrical installation must be disconnected from life parts on all poles..
2) Secure against reconnection
3) verify that the installation is dead
4) Carry out earthing and short circuiting
5) provide protection against adjacent live parts

Which term correctly completes the following statement?

A three-dimensional object has a(n) _____ measurement recorded in _____ units.


volume, cubic

volume, square

area, cubic

area, square

Answers

Answer:

Explanation:

The correct term to complete the statement is:

A three-dimensional object has a(n) volume measurement recorded in cubic units.

Volume is a measure of the amount of space an object takes up in three dimensions, and is measured in cubic units (such as cubic centimeters, cubic meters, or cubic inches).

Area, on the other hand, is a measure of the amount of surface covered by an object in two dimensions, and is measured in square units (such as square centimeters, square meters, or square inches). Therefore, options B and C are incorrect.

Option D is also incorrect because area is not a measurement used to describe a three-dimensional object.

Explain why Chloe's design needs to be redone in the following scenario, and recommend the techniques she needs to include in her sketches.
Chloe has drawn a design of a new supermarket She has added all of her detail to one isometric sketch. The design was not done to scale, and the construction team is not sure how large the
building will be once it is complete.

Answers

Answer:

The correct answer includes that her sketch should also include an orthographic view. She also needs to incorporate ratios to proportions so the team will know the scale of the design. She can use customary units for her measurements, as well as an engineer’s scale and a computer program to assist her with the dimensions.

The pressure gradient may be caused by a pump and/or gravity.

If a 10-kilogram [kg] rotating solid cylinder moves at a velocity (v), it has a kinetic energy of 36 joules [J]. Determine the velocity the object is moving in units of meters per second [m/s] if the kinetic energy is given by KE=12/mv2+14/mv2.

Answers

Answer:

v = 2.68 m/s

Explanation:

Given that,

Mass of a solid cylinder, m = 10 kg

The kinetic energy of a solid cylinder, K = 36 J

We need to find the velocity of the object. The formula for the kinetic energy is given by :

[tex]K=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2K}{m}} \\\\v=\sqrt{\dfrac{2\times 36}{10}} \\\\v=2.68\ m/s[/tex]

So, the velocity of the object is 2.68 m/s.

Which fields of engineering use fluid power? Explain how these fields make use of fluid power systems: water supply, agricultural equipment, construction, and earth-moving equipment.

Answers

Answer:

Some fields of engineering that use fluid power are construction, heavy equipment, metallurgy, manufacturing, and oil and gas.

Water supply systems consist of these hydraulic components:

Pipes: Pipes transport water around the system. They are primary feeders (large-diameter pipes), secondary feeders (medium-diameter pipes), and distributors (small-diameter pipes).

Valves: They control the direction of the water flow. Indicating valves convey whether they are open or closed and non-indicating valves do not.

Hydrants: Hydrants appear at periodic intervals along the underground pipe network to provide water for firefighting.

Storage containers: Tanks located at a height provide water when demand is higher than supply. Gravity provides the required water pressure. Pumps can elevate water and refill the tank.

Agricultural equipment: Machines with hydraulic conveyors help transport harvested crops to wagon trailers.

In the construction industry, industrial forklifts lift and transport heavy weights. Hydraulic cylinders can tilt, lower, or elevate the required weight in a smooth motion.

Earth-moving equipment such as excavators have hydraulically powered buckets that can dig up ground, carry soil in the bucket, and drop the soil into trucks.

When you are climbing a hill on a bike with different speeds, why does it seem like you are pedaling a lot to cover a short distance? What happens if you switch to a higher gear in hopes of not having to pedal as much?

Answers

It seems like your pedaling a lot because it takes more energy and is way slower than a regular road. It you switch to the higher gear it will make you go slower because it is made for going down hill or going high speeds and a lower gear will help you more cause its easier and it will make it go faster.

The reason why it seems you have to cover a short distance when pedaling up the hill is explained in Paragraph 2 below.

What will happen if you switch to a higher gear hoping you wouldn't pedal too much is explained in paragraph 3 below.

Bikes are usually configured in such a way that the mechanical advantage which is the ratio of output force to input force will increase when there is an increase in resistance like the question  shows by climbing a hill.

Now, since there is resistance from climbing the hill on the bike, it means that you must increase your effort by completing more revolutions since the bike tires itself would not complete that much revolutions required to counter the trade off distance.

Finally, if you decide to switch to a higher gear it means it will become very difficult to pedal since you need power to do so.

the stiffness, or tension of a spring is called what

Answers

Answer: sprung Weight

Explanation: Spring Rate. refers to the stiffness, or tension, of a spring. Sprung Weight. the weight of the parts that are supported by the springs and suspension systems.

Simply said, springs of one kind or another, such as coiled springs, air springs, and Belleville springs, sustain the sprung weight of a vehicle. As wheels drive over bumps, potholes, and other obstacles, unsprung weight rises and falls with them.

What the stiffness, or tension of a spring?

The part of the vehicle's overall mass that is carried by the suspension, as well as in most applications roughly half of the suspension's weight. It is referred to as sprung mass (or sprung weight) in vehicles with suspensions like cars, motorcycles, or tanks.

Spring rate. Relates to the tension or stiffness of a spring. Lifted Weight. The mass of the components that the suspension and spring systems are designed to support.
