A Hartnell governor has two rotating balls, of mass 2.7 kg each. The ball radius is 125 mm in the mean position when the
ball arms are vertical and the speed is 150 r.p.m. with the sleeve rising. The length of the ball arms is 140 mm and the
length of the sleeve arms 90 mm. The stiffness of the spring is 7 kN/m and the total sleeve movement is 12 mm from the
mean position. Allowing for a constant friction force of 14 N acting at the sleeve, determine the speed range of the
governor in the lowest and highest sleeve positions. Neglect the obliquity of the ball arms

The use GCF method is correctly illustrated recursively below
What is GCF (Greatest common factor)The GCF is the greatest common factor that can be used to correctly divide two or more numbers without a reminder.
For example,
The parameters 20 and 30, to know the greatest common factor, write out each factors of 20 and 30
The factors of 20 = 1, 2, 4, 5, 10, and 20
The factors of 30 = 1, 2, 3, 5, 6, 10, 15, and 30

Conduct online research and write a short report on the origin and evolution of the meter as a measurement standard. Discuss how the meter formed a base for the development of other measuring standards.
Answer:
People have come up with all sorts of inventive ways of measuring length. The most intuitive are right at our fingertips. That is, they are based upon the human body: the foot, the hand, the fingers or the length of an arm or a stride.
In ancient Mesopotamia and Egypt, one of the first standard measures of length used was the cubit. In Egypt, the royal cubit, which was used to build the most important structures, was based on the length of the pharaoh’s arm from elbow to the end of the middle finger plus the span of his hand. Because of its great importance, the royal cubit was standardized using rods made from granite. These granite cubits were further subdivided into shorter lengths reminiscent of centimeters and millimeters.

Later length measurements used by the Romans (who had taken them from the Greeks, who had taken them from the Babylonians and Egyptians) and passed on into Europe generally were based on the length of the human foot or walking and multiples and subdivisions of that. For example, the pace—one left step plus one right step—is approximately a meter or yard. (On the other hand, the yard did not derive from a pace but from, among other things, the length of King Henry I of England’s outstretched arm.) Mille passus in Latin, or 1,000 paces, is where the English word “mile” comes from.
And thus, the meter has and likely will remain so elegantly defined in these terms for the foreseeable future.

How many hours must be traveled by car for each hour of rock climbing to make the
risks of fatality by car equal to the risk of fatality by rock climbing? (FAR for car
travelling is 52 and FAR for rock climbing is 3400).
The number of hours that must be travelled by car to make the risks of fatality by car equal to the risk of fatality by rock climbing is = 65hours
Calculation of risk of fatalities (FAR)The FAR of car = 52
This means for every one hour there is risk of 52 people dying by car accident.
The FAR of rock climbing = 3400
This means that for every one hour there is risk of 3400 dying by car accident.
If FAR for 1 hour = 52
X hours = 3400
Make X the subject of formula,
X hours = 3400/52
= 65 hours approximately
Therefore, the number of hours that must be travelled by car to make the risks of fatality by car equal to the risk of fatality by rock climbing is = 65 hours.

The end of a cylindrical liquid cryogenic propellant tank in free space is to be protected from external (solar) radiation by placing a thin metallic shield in front of the tank. Assume the view factor Fts between the tank and the shield is unity; all surfaces are diffuse and gray, and the surroundings are at 0 K. It is given that Tt= 100 K, ε1=ε2= 0. 10, εt= 0. 20, and GS= 1250 W/m2.
If the temperature of the shield is 338 kelvin. Then the heat flux through the tank will be 25.3 Watt per square meter.
What is heat flux?The increase in heat energy movement through a particular surface is known as heat flux, and the heat flux density is the absolute temperature per unit area.
Assume the view factor between the tank and the shield is unity; all surfaces are diffuse and gray, and the surroundings are at 0 K.
It is given that T= 100 K, ε₁ = ε₂ = 0. 10, [tex]\varepsilon_t[/tex] = 0.20, and GS= 1250 W/m².
Then we have
The temperature of the shield will be
[tex]\rm \alpha _sG_s - \varepsilon _1 E_b (T_s) - \dot{q}_{ST} = 0[/tex] ...1
and
[tex]\rm q''_{12}=\dfrac{ \sigma (T_{1}^{4} - T_{2}^{2})}{\frac{1}{\varepsilon _1 }+ \frac{1}{\varepsilon _2} -1}}[/tex] ...2
Then from equations 1 and 2, we have
[tex]\rm \alpha _sG_s - \varepsilon _1 E_b (T_s) - \dfrac{ \sigma (T_{1}^{4} - T_{2}^{2})}{\frac{1}{\varepsilon _1 }+ \frac{1}{\varepsilon _2} -1}} = 0[/tex]
Then the value of [tex]\rm T_s[/tex] will be
[tex]\rm T_s =\left [ \dfrac{\alpha _sGs+\left ( \dfrac{\sigma T_1^4}{\frac{1}{\varepsilon _1}+\frac{1}{\varepsilon _2} - 1} \right )}{\sigma \left ( \varepsilon _1 + \dfrac{1}{\frac{1}{\varepsilon _1} + \frac{1}{\varepsilon _2}-1} \right )} \right ] ^{\dfrac{1}{4}}[/tex]
Put all the values, then we have
[tex]\rm T_s = \left [ \dfrac{0.05 \times + \left ( \dfrac{\sigma (100)^4}{\frac{1}{0.1}+\frac{1}{0.05}-1} \right )}{\sigma \left ( 0.05 + \dfrac{1}{\frac{1}{0.1}+\frac{1}{0.05} - 1} \right )} \right ]^{\dfrac{1}{4}} \\\\\\T_s = 338 \ K[/tex]
