Answer:
a) the temperature to which the pin must be cooled for assembly is 
b) the radial pressure at room temperature after assembly is 
c) the safety factor in the resulting assembly = 6.4
Explanation:
Coefficient of thermal expansion 
Yield strength 
= 400 MPa
Modulus of elasticity (E) = 209 GPa
Room Temperature 
= 20°C
outer diameter of the collar 
inner diameter of the collar
pin diameter 
= 
Clearance c = 0.06 mm
a)
The temperature to which the pin must be cooled for assembly can be calculated by using the formula:
-0.09 = 
-0.09 = 
=
−0.07523262 =
b)
To determine the radial pressure at room temperature after assembly ;we have:
c) the safety factor of the resulting assembly is calculated as:
safety factor = 
safety factor = 
safety factor = 6.4
Thus, the safety factor in the resulting assembly = 6.4
Answer:
The viscosity of the fluid is 6.05 Pa-s
Explanation:
The viscosity obtained from a rotating type viscometer is given by the equation
where
T is the torque applied in the viscometer
't' is the thickness of gap
is the angular speed of rotation
are the outer and the inner raddi respectively
Since it is given that
Applying the values in the above relation we get
Answer:
1913meter per second square.

Answer:
C. The vehicle safety check indicates the ABS is functioning normally.
Explanation:
ABS, an antilock braking system, is a safe and secure slip-resistant braking system in cars and air-crafts. <u>An ABS is there to prevent wheel-locking while using brakes in vehicles</u>.
When one ignites a car, the ABS indicator will light up briefly as a part of safety check.<em> The ABS indicator light comes on for a few seconds before it turns off again. This indicates that the ABS system is functioning normally</em>. But, if the ABS indicator light remains after turning on the ignition, this indicates that there is a problem in the system.
In the given scenario, the ABS indicator is functioning properly, thus the correct answer is the third option (C).
Answer:
(a). max possible efficiency = 55.62%
(b). max power output = = 133.5 MW
Explanation:
From the question we were given the Maximum temperature in the system as
Tmax = 500°C
Minimum temperature in the system Tmin = 70°C
the Heat supplied to the boiler Qb = 240000 KJ/s
we use the temperature conversion factor from °C to K
given T(K) = T (°C) + 273
⇒ Tmax = 500 + 273 = 773 K
⇒ Tmin = 70 + 273 = 343 K
(a). we are to determine the maximum possible thermal efficiency;
(Πth)max = 1 - Tmin/Tmax
(Πth)max = 1 - 343/773 = 0.5562
(Πth)max = 55.62%
(b). to determine the maximum possible power output for the plant we have;
(Πth)max = Wmax/Qb
where Wmax rep the maximum power output
(Πth)max = 0.5562
Qb = 240000
∴ Wmax = 0.5562 × 240000 = 133505.6 Kw
Wmax = 133.5 MW
