Consider steady, incompressible, laminar flow of a Newtonian fluid in an infinitely long round pipe annulus of inner radius Ri and outer radius Ro Ignore the effects of gravity. A constant negative pressure gradient _P/_x is applied in the x-direction, (∂P/∂x)=(P1-P2)/(x2-x1) where x1 and x2 are two arbitrary locations along the x-axis, and P1 and P2 are the pressures at those two locations. The pressure gradient may be caused by a pump and/or gravity. Note that we adopt a modified cylindricaloordinate system here with x instead of z for the axial component, namely, ( r, θ ,x) and (Ur, Uθ ,Ux) Derive an expression for the velocity field in the annular space in the pipe.

How do you determine when a truss will fail?
(Yield Stress)

Answers

Answer:

If a truss buckles or overturns, it is usually because of the failure of an adjacent truss or its bracing. A steel truss in a fire may buckle and overturn because of expansion or weakening from the heat. Most truss failures are the result of broken connections. Photo 1 shows a set of parallel-chord wood trusses supporting a plywood floor deck.

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.

Therefore, the stiffness, or tension of a spring is called what sprung Weight

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.

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.
