Answer:
gravity force or weight
You are diving a car out in rural America and suddenly you get a flat tire. you pull off to the side of the road. you check your cell reception and dont have a single bar of signal (your cell phone won't work). you look around and there is no other cars or houses anywhere in sight and you do not remember the last time you saw a passing car or house. you are absolutely alone. the sun is setting and it is just starting to get dark. you get out and jack up the car, loosen the 4 nuts, take off the wheel with the flat tire. you grab the spare from the trunk and slide it onto the axle- you then look around for the 4 nuts and they are no where to he found. you search everywhere and cant find them. its gettint cold and dark. you look at the car, what can you do? all four of the nuts from the wheel have vanished snd are just gone. explain what you can do and why? remember, you cant call anyone because there is no reception, there is no one else on the road and you havent seen anyone in hours, its getting dark and cold, the 4 nuts from the wheel are gone, the car cannot drive safely with only 3 wheels

A 4.0 in. wide by 1.125 in. thick rectangular steel bar supports a load of P in tension. Determine:
• The stress in the bar for F = 32,000 lb.
• The load P that can be supported by the bar if the axial stress must not exceed 25,000 psi.
Answer:
a) The stress in the bar when F is 32,000 is approximately 7,100 psi
b) The load P that can be supported by the bar if the axial stress must not exceed is approximately 110,000 lb
Explanation:
The question topic relates to stresses in structures;
The given parameters of the steel bar are;
The width of the steel bar, W = 4.0 in.
The thickness of the steel bar, t = 1.125 in.
The formula for stress in a bar is given as follows;
[tex]Stress, \sigma = \dfrac{Force, F}{Area, A}[/tex]
The cross sectional area of bar, A = W × t = 4.0 in. × 1.125 in. = 4.5 in.²
∴ The cross sectional area of bar, A = 4.5 in.²
a) The stress in the bar for F = 32,000 lb, is given as follows;
[tex]The \ stress \ in \ the \ bar , \sigma = \dfrac{ F}{A} = \dfrac{32,000 \ lb}{4.5 \ in.^2} = 7,111.\overline 1[/tex]
The stress in the bar when F is 32,000 is σ = 7,111.[tex]\overline 1[/tex] psi ≈ 7,100 psi
b) The load P that can be supported by the bar if the axial stress must not exceed, σ = 25,000 psi is given as follows;
[tex]\sigma = \dfrac{ P}{A}[/tex]
Therefore;
P = σ × A = 25,000 psi × 4.5 in² = 112,500 lb
For the axial stress of 25,000 psi not to be exceeded, the maximum load that can be supported by the bar, P = 112,500 lb ≈ 110,000 lb.

Which is the best description of power? A. the amount of kinetic energy lost during motion
B. a measure of how fast an object can travel
C. the amount of energy transfer during motion
D. a measure of how fast a machine performs work
Answer:
D. a measure of how fast a machine performs work
Explanation:
Power can be defined as the energy required to do work per unit time.
Mathematically, it is given by the formula;
[tex] Power = \frac {Energy}{time} [/tex]
Hence, the best description of power is that, it is a measure of how fast a machine performs work.
This can be calculated by using the mathematical expression below;
[tex] Power = \frac {Work done}{Time} [/tex]
But we know that, [tex] Workdone = force * distance [/tex]

Answer:
x = 3.92
Explanation:
The question is given as ;
40 = 6x² / 4 tan { 180/6}
40 = 6x² / 4 tan {30°}
40 = 6x² / 2.309
40 * 2.309 = 6x²

when changing a rivet dies on a rivet gun, you should make sure
Answer:
Installing solid rivets in an aircraft structure requires considerably more know-how and skill than does working with pop rivets. For one thing, you can install those hollow-core pop rivets working alone with only a simple hand operated pop riveter . . . even if you don't have access to the back side of the parts being riveted together. It is sometimes called "blind riveting".
Unfortunately, it's quite different with solid rivets. You do not enjoy the luxury of that pop rivet "blind" feature because you absolutely must have access to both sides of the parts being riveted. Sometimes it even takes two people. Furthermore, you will have to become proficient in the use of a few special tools.

In "Rabbitville", the rabbit population squares each year. e.g. If you start with 4 rabbits, you'll have 16 in 1 year, and 256 in 2 years. Once the population exceeds 10,000 bunnies, food will be scarce, and population will begin to decrease.
Write a function years_till_no_carrots that includes a WHILE loop. Given a single integer (# of starting rabbits) as an input, your function should output the number of whole years until the number of rabbits becomes larger than 10000. e.g. years_till_no_carrots(4) = 3 (start with 4 rabbits, population greather than 10000 & food scarce in 3 years)
Answer:
In Python:
def years_till_no_carrots(n):
year = 0
while(n <= 10000):
n=n**2
year = year + 1
return year
Explanation:
First, we define the function
def years_till_no_carrots(n):
Next, the number of years is initialized to 0
year = 0
The following while loop is iterated until the population (n) exceeds 10000
while(n <= 10000):
This squares the population
n=n**2
The number of years is then increased by 1, on each successive iteration
year = year + 1
This returns the number of years
return year
To call the function from main, use (e.g): print(years_till_no_carrots(4))
