An aluminum rod is press fitted onto an aluminum collar. The collar has an inner radius of 1 cm and an outer radius of 2 cm. Given the rod has a diameter of 2.01cm and the young's modulus of aluminum is 69 GPa
The question is incomplete. The complete question is --
An aluminum rod is press fitted onto an aluminum collar. The collar has an inner radius of 1 cm and an outer radius of 2 cm. Given the rod has a diameter of 1.01 cm and the young's modulus of aluminum is 69 GPa, determine the following :
1. the interference value, i
2. the radial pressure at the interference of the collar and the rod
3. the maximum effective stress in the collar
4. if the yield strength of aluminium is 200 MPa and assume a safety factor of 1.5, will the aluminium collar break
Solution:
Given :
Inner radius of the collar = 1 cm
So, inner diameter, [tex]$d_1$[/tex] = 2 cm
Outer radius of the collar = 12 cm
So, outer diameter, [tex]$d_2$[/tex] = 4 cm
The aluminium rod diameter, d = 1.01 cm
Now, from the figure, we can see that there will be no interference and so the rod will easily insert inside the collar.
1. So, the interference , i =0
2. The radial pressure is also 0.
3. There will be no stress developed. So the maximum effective stress is 0
4. The collar will not break
Explain the major differences between designing buildings for earthquake resistance and for wind resistance.
Answer:
Earthquake's put vibration and seismic load on a building while wind puts a continuous force throughout the whole structure.
Explanation:
The most important difference between the design of a building that's resistent to earthquakes and resistant to high speed winds is that earthquake's put vibration and seismic load on a building while wind puts a continuous force throughout the whole structure.
Earthquake resistent building are equipped with a base that is isolated from the buildings with several layers of different material which absorb the vibration of the seismic waves and prevent them from reaching to the building.
Wind resistent buildings must have strong foundations and a sturdy structure/material that can withstand high pressure that the wind applies during events such as hurricanes.

A typical printed page of text contains 50 lines of 80 characters each. Imagine that a certain printer can print 6 pages per minute and that the time to write a character to the printer’s output register is so short it can be ignored. Does it make sense to run this printer using interrupt‐driven I/O if each printer requires an interrupt that takes 50 µsec all‐in to service?
Solution :
Given
The number of line that can be written by printer per page = 50 lines
The number of characters that can be written by printer per page = 80 characters.
Number of pages that can be written per minute = 6 pages
The speed for writing characters to the printer can be found by
= 50 x 80 x 6
= 400 characters per sec
In one second the printer has the writing speed of 400 character.
Now each of the character uses = 50 µsec of the CPU time for interrupt.
So in each second, the interrupt overhead = 20 msec
Now using the interrupt driven input/output, 980 msec time can be available for other work.
Thus, the interrupt overhead charges only 2 percent of the CPU, that will hardly affect the program to run.

Explanation:
Two routes connect an origin and a destination. Routes 1 and 2 have performance functions t1 = 2 + X1 and t2 = 1 + X2, where the t's are in minutes and the x's are in thousands of vehicles per hour. The travel times on the routes are known to be in user equilibrium. If an observation for route 1 finds that the gaps between 30% of the vehicles are less than 6 seconds. Estimate the volume and average travel times for the two routes
Solution :
Given
[tex]$t_1=2+x_1$[/tex]
[tex]$t_2=1+x_2$[/tex]
Now,
[tex]$P(h<5)=1-P(h \geq5)$[/tex]
[tex]$0.4=1-P(h \geq5)$[/tex]
[tex]$0.6=P(h \geq5)$[/tex]
[tex]$0.6= e^{\frac{-x_1 5}{3600}}$[/tex]
Therefore, [tex]$x_1=368 \ veh/h$[/tex]
[tex]$=\frac{368}{1000} = 0.368$[/tex]
Given, [tex]$t_1=2+x_1$[/tex]
= 2 + 0.368
= 2.368 min
At user equilibrium, [tex]$t_2=t_1$[/tex]
∴ [tex]$t_2$[/tex] = 2.368 min
[tex]$t_2=1+x_2$[/tex]
[tex]$2.368=1+x_2$[/tex]
[tex]$x_2 = 1.368$[/tex]
[tex]$x_2 = 1.368 \times 1000$[/tex]
= 1368 veh/h
Discuss the aging that occurs in asphalt cement during mixing with aggregates and in service. How can the different types of aging of asphalt cement be simulated in the laboratory?
Answer:
It can be simulated with RTFO and PAV method
Explanation:
The aging which occurs for the binders is always tested using rolling thin film oven and also pressure aging vessels. The rolling thin film oven is a method used to calculate the short term aging that occurs in the asphalt cement when it mixes with the aggregates as well as in service. While the long term process of aging in asphalt cement is carried out by pressure aging vessel.
The short term process of aging can be simulated with the help of RTFO and the long term is simulated by the PAV method.

Discoloration on walls, work surfaces, ceilings, walls, and pipes may indicate a leak that is causing you to waste raw materials.
Answer:
True :)
Explanation:
If this is a true or false question.
The discoloration is when the color of a particular thing comes off or changes, fading from its original color. In other words, when the original color of anything changes or wanes off, then that is called discoloration. The statement is true.
What is Discoloration?This chemical shift occurs for a number of reasons, including its interaction with other elements nearby or the unfavorable effects of other elements it comes into touch with.
Water leaks may create cases of discoloration on walls, surfaces, even ceilings, and pipes. As a result, the surface progressively changes and becomes moist.
Discoloration puts the surrounding region in danger in addition to altering the part(s) or area's look and durability.
Since a change in that region or component is required, the raw material(s) used are wasted. The claim that discoloration results in the waste of raw materials are thus accurate.

2) The switch in the circuit below has been closed a long time. At t=0, it is opened.
Find the inductor current for il(t) for t> 0.
Answer:
il(t) = e^(-100t)
Explanation:
The current from the source when the switch is closed is the current through an equivalent load of 15 + 50║50 = 15+25 = 40 ohms. That is, it is 80/40 = 2 amperes. That current is split evenly between the two parallel 50-ohm resistors, so the initial inductor current is 2/2 = 1 ampere.
The time constant is L/R = 0.20/20 = 0.01 seconds. Then the decaying current is described by ...
il(t) = e^(-t/.01)
il(t) = e^(-100t) . . . amperes

A rigid, insulated vessel is divided into two equal-volume compartments connected by a valve. Initially, one compartment con tains 1 m3 of water at 20°C, x = 50%, and the other is evacuated. The valve is opened and the water is allowed to fill the entire volume. For the water, determine the final temperature, in °C, and the amount of entropy produced, in kJ/K.
Solution :
Given
Volume, [tex]$V_1 = 1 \ m^3$[/tex]
Temperature, [tex]$T_1=20 \ ^\circ C[/tex]
[tex]$x_1=0.5$[/tex]
From the saturated water table, corresponding to [tex]$T_1=20 \ ^\circ C[/tex], we get the saturated liquid, vapor specific and the entropy.
[tex]$v_f=1.0010 \ m^3/kg$[/tex]
[tex]$v_g=57.791 \ m^3/kg$[/tex]
[tex]$s_f=0.2966 \ kJ/kg-K$[/tex]
[tex]$s_g=8.6672 \ kJ/kg-K$[/tex]
Now calculating the initial specific volume
[tex]$v_1=v_f+x_1 \cdot(v_g-v_f)$[/tex]
[tex]$=1.0018+05 \cdot(57.791-1.0018)$[/tex]
[tex]$= 29.8973 \ m^3/kg$[/tex]
Calculating the initial specific entropy:
[tex]$s_1=s_f+x+1 \cdot (s_g-s_f)$[/tex]
[tex]$=0.2966+0.5 \cdot (8.6673 - 0.2966)$[/tex]
[tex]$= 4.48 \ kJ/kg-K$[/tex]
So final volume of the vessel is two times bigger as the initial volume
[tex]$V_2=2 .V_1$[/tex]
[tex]$= 2 \times 29.8973 = 59.8 \ m^3/kg$[/tex]
If we interpolate the values from tables between [tex]$v_g=57.791 \ m^3/kg$[/tex] and [tex]$v_g=61.293 \ m^3/kg$[/tex], we can get final temperature and specific entropy corresponding to value of [tex]$v_2$[/tex] :
Final temperature, [tex]$T_2= 19.6 ^\circ C$[/tex]
and [tex]$s_2 = 8.68 \ kJ/kg-K$[/tex]
Calculating change in entropy
[tex]$\Delta s = s_2-s_1$[/tex]
[tex]$=8.68-4.48 = 4.2 \ kJ/kg-K$[/tex]

A room is filled with saturated moist air at 25°C and a total pressure of 100 kPa. If the mass of dry air in the room is 100 kg, the mass of water vapor is:_______
a. 0.52 kg
b. 1.97 kg
c. 2.96 kg
d. 2.04 kg
e. 3.17 kg
Answer:the mass of water vapor is=d. 2.04 kg
Explanation:
The humidity ratio by mass is given as
x = mw / ma (1)
where
mw = mass of water vapor
ma = mass of dry air
And also humidity ratio by pressure by Ideal Gas Law is given as
x = 0.62198 pw / (pa - pw) (2)
where
pw = partial pressure of water vapor in moist air
pa = atmospheric pressure of moist air
Equating both equation we have that
Humidity ratio = 0.62198 pw / (pa - pw)= mw / ma (3)
From the from the water table at 25°C,
water vapor partial pressure = 23.8 torr
1 atm =760 torr.
1 atm = 101.325 kPa,
So, 760 torr =101.325 kPa,
Therefore 23.8 torr =3.173kPa
Humidity ratio = 0.62198 pw / (pa - pw)= mw / ma
0.62198 x 3.173 / (100-3.173)= mw / 100
1.9736 /96.827=mw/100
0.0204=mw/100
mw=2.04kg

The maximum dry density in lb/ft3 is most nearly:_______
Answer:
115 Ib/ft^3
Explanation:
To determine the maximum dry density in Ib/ft3 we have to calculate :
Bulk unit weight ( yb ) ; W / v
Dry unit weight ( yd. ) : yb / ( 1 + w )
For every set of data given
assuming v = 1/30 ft^3
calculating for the 3 data set ( maximum dry density )
weight of soil (W) = 4.40
moisture content (%) (w) = 15.0 = 0.15
Bulk unit weight (yb) = 4.40 / (1/30) = 132 Ib/ft^3
Dry unit weight ( yd. ) = 132 / ( 1 + 0.15 ) = 114.702 Ib/ft^3
therefore after calculations the maximum dry density in Ib/ft^3 ≈ 115 Ib/ft^3
