seropon [69]

Answer:

net force acting on the floor is 100 kN

Explanation:

Given data:

$P_{vaccum} = 0.1 kPa$

$P_{atm} = 101.325 kPa$

dimension of floor = 2 m \times 0.5 m

we know that

Net force can be calculated as follow

$f_{net} = P_{vaccum} \times area$

$f_{net} = 0.1\times 10^3 \times 2\times 0.5$

$f_{net} = 0.1\times 10^3 \times 1$

$f_{net} = 100 kN$

Therefore net force acting on the floor is 100 kN

What are some of the most complex building types to design?.

OLga [1]

Strangely enough, the most complex building to design is the common house. I know, they’re like belly buttons, even if you don’t have one yourself, you know someone that has one, and you’ve certainly been in one.

A house has all the ingredients that you will find in far more complex buildings. On top of that, they are there in small quantities.

Nearly every house has a kitchen, bathroom, laundry and toilet. You will also find some of these in hospitals, hotels, parking stations, office blocks, sewerage works, defence facilities and so on.

The only difference is that in a house, there may only be one of these and it must be the right size, shape and position so that it is suitable for use. Even the doorways must be positioned correctly - to allow for ventilation, light, privacy , ease of access, safety and even feng-shui.

Each room must be the right size for its’ occupants and its’ usage. Bedrooms should have a window or some other method of providing natural light. Toilets and bathrooms should allow for privacy.

The materials that it is built of should be fit for purpose. The roof should provide shelter from the elements. The walls should be able to support the weight of the roof and provide shelter and security for the occupants. The floor should be stable and strong and able to support the activities that are carried out in the house.

On top of all that, it must look good - to somebody. It also must be comfortable to live in, otherwise the design is a fail. That doesn’t mean that it shouldn’t be cheap to build. A good designer designs with one eye on the asthetics, the other eye on the usage and utility and his hand firmly closed around the cheque-book.

A particular competition has five judges, each of whom award a score between 0 and 10 to each performer. • Fractional scores, su

Anettt [7]

Answer:

Explanation:

Lets do this in python, our function will import an array of double numbers, then it sort the array out, drop the first and last items, aka highest and lowest score. Finally, it averages the last 3 numbers by calculate the sum and divide by the number of items

def calculate_score(scores):

scores.sort() # sort it so that the lowest is at index 0 and the highest is at last index

drop_highest_lowest = scores[1:-1] # this will drop the lowest and highest number

average_score = sum(drop_highest_lowest)/len(drop_highest_lowest)

return average_score

The phasor technique makes it pretty easy to combine several sinusoidal functions into a single sinusoidal expression without us

devlian [24]

Answer:

The phasor technique can't be applied directly in the following cases:

a) 45 sin(2500t – 50°) + 20 cos(1500t +20°)

b) 100 cos(500t +40°) + 50 sin(500t – 120°) – 120 cos(500t + 60°)

c) -100 sin(10,000t +90°) + 40 sin(10, 100t – 80°) + 80 cos(10,000t)

d) 75 cos(8t+40°) + 75 sin(8t+10°) – 75 cos(8t + 160°)

Explanation:

For a) and c), it is not possible to use the phasor technique, due this technique is only possible when the sinusoidal signals to be combined are all of the same frequency.

This is due to the vector representing a signal is showed as a fixed vector in the graph( which magnitude is equal to the amplitude of the sinusoid and his angle is the phase angle with respect to cos (ωt)), which is rotating at an angular speed equal to the angular frequency of the sinusoidal signal that represents, like a radius that shows a point rotating in a circular uniform movement.

This rotating vector represents a sinusoidal signal, in the form of a cosine (as the real part of the complex function $e^{j(wt+\alpha)}$ ), so it is not possible to combine with functions expressed as a sine, even though both have the same frequency.

If we look at the graphs of cos (ωt) and sin (ωt) we can say that the sin lags the cos in 90º, so we can say the following:

sin (ωt) = cos (ωt-90º)

This means that in order to be able to represent a sine function as a cosine, we need to rotate it 90º in the plane clockwise.

This is the reason why before doing this transformation, it is not possible to use the phasor technique for b) and d).
