Answer:
The required rated input apparent power is 14.98 HP
Explanation:
Real power input = real power output ÷ efficiency
real power output = 12 HP
efficiency = 90% = 0.9
Real power input = 12 ÷ 0.9 = 13.33 HP
Apparent power input = real power input ÷ power factor = 13.33 ÷ 0.89 = 14.98 HP
Answer:
Area required = 9.5 ft²
Explanation:
Step by step explanation is given in the attached document.
Answer:
The right answer is "1.903 m".
Explanation:
Given that,
![\tau =110 \ MPa](https://tex.z-dn.net/?f=%5Ctau%20%3D110%20%5C%20MPa)
![G=80 \ GPa](https://tex.z-dn.net/?f=G%3D80%20%5C%20GPa)
![\Theta=15\times \frac{\pi}{180}](https://tex.z-dn.net/?f=%5CTheta%3D15%5Ctimes%20%5Cfrac%7B%5Cpi%7D%7B180%7D)
![=\frac{\pi}{12}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Cpi%7D%7B12%7D)
![d=20 \ mm](https://tex.z-dn.net/?f=d%3D20%20%5C%20mm)
As we know,
⇒ ![\frac{\tau}{r}=\frac{G \Theta}{L}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctau%7D%7Br%7D%3D%5Cfrac%7BG%20%5CTheta%7D%7BL%7D)
Or,
⇒ ![L=\frac{G \theta r}{\tau}](https://tex.z-dn.net/?f=L%3D%5Cfrac%7BG%20%5Ctheta%20r%7D%7B%5Ctau%7D)
![=\frac{80\times 10^3}{110}\times \frac{\pi}{12}\times 10](https://tex.z-dn.net/?f=%3D%5Cfrac%7B80%5Ctimes%2010%5E3%7D%7B110%7D%5Ctimes%20%5Cfrac%7B%5Cpi%7D%7B12%7D%5Ctimes%2010)
![=1903.9 \ mm](https://tex.z-dn.net/?f=%3D1903.9%20%5C%20mm)
or,
![=1.903 \ m](https://tex.z-dn.net/?f=%3D1.903%20%5C%20m)
Answer:
fracture will occur as the value is less than E/10 (= 22.5)
Explanation:
If the maximum strength at tip Is greater than theoretical fracture strength value then fracture will occur and if the maximum strength is lower than theoretical fracture strength then no fracture will occur.
![\sigma_m = 2\sigma_o [\frac{a}{\rho_t}]^{1/2}](https://tex.z-dn.net/?f=%5Csigma_m%20%3D%202%5Csigma_o%20%5B%5Cfrac%7Ba%7D%7B%5Crho_t%7D%5D%5E%7B1%2F2%7D)
![= 2\times 750 (\frac{\frac{0.2mm}{2}}{0.001 mm}})^{1/2}](https://tex.z-dn.net/?f=%3D%20%202%5Ctimes%20750%20%28%5Cfrac%7B%5Cfrac%7B0.2mm%7D%7B2%7D%7D%7B0.001%20mm%7D%7D%29%5E%7B1%2F2%7D)
= 15 GPa
fracture will occur as the value is less than E/10 = 22.5
Answer:
Tech A is correct
Explanation:
Tech A is right as its V- angle is identified by splitting the No by 720 °. Of the piston at the edge of the piston.
Tech B is incorrect, as the V-Angle will be 720/10 = 72 for the V-10 motor, and he says 60 °.
