Answer:
Shearing strain will be 0.1039 radian
Explanation:
We have given change in length ![\Delta L=0.12inch](https://tex.z-dn.net/?f=%5CDelta%20L%3D0.12inch)
Length of the pad L = 1.15 inch
We have to find the shearing strain
Shearing strain is given by
![\alpha =tan^{-1}\frac{\Delta L}{L}=tan^{-1}\frac{0.12}{1.15}=5.9571^{\circ}](https://tex.z-dn.net/?f=%5Calpha%20%3Dtan%5E%7B-1%7D%5Cfrac%7B%5CDelta%20L%7D%7BL%7D%3Dtan%5E%7B-1%7D%5Cfrac%7B0.12%7D%7B1.15%7D%3D5.9571%5E%7B%5Ccirc%7D)
Shearing strain is always in radian so we have to change angle in radian
So ![5.9571\times \frac{\pi }{180}=0.1039radian](https://tex.z-dn.net/?f=5.9571%5Ctimes%20%5Cfrac%7B%5Cpi%20%7D%7B180%7D%3D0.1039radian)
Answer:
The grinding machine is used for roughing and finishing flat, cylindrical, and conical surfaces; finishing internal cylinders or bores; forming and sharpening cutting tools; snagging or removing rough projections from castings and stampings; and cleaning, polishing, and buffing surfaces.
Answer:
Both Technician A and B are correct.
Explanation: Both are correct, but keep note that different color coolants leave different color stains.
Admission to the Engineering course at Cambridge is highly competitive, both in terms of the numbers and quality of applicants. In considering applicants, Colleges look for evidence both of academic ability and of motivation towards Engineering. There are no absolute standards required of A Level achievement, but it should be noted that the average entrant to the Department has three A* grades. You need to get top marks in Maths and Physics.All Colleges strongly prefer applicants for Engineering to be taking a third subject that is relevant to Engineering.
Hope that helps and good luck if you are applying. Can you please mark this as brainliest and press the thank you button and if you have any further questions please let me know!!
Answer:
The pressure difference across hatch of the submarine is 3217.68 kpa.
Explanation:
Gauge pressure is the pressure above the atmospheric pressure. If we consider gauge pressure for finding pressure differential then no need to consider atmospheric pressure as they will cancel out. According to hydrostatic law, pressure varies in the z direction only.
Given:
Height of the hatch is 320 m
Surface gravity of the sea water is 1.025.
Density of water 1000 kg/m³.
Calculation:
Step1
Density of sea water is calculated as follows:
![S.G=\frac{\rho_{sw}}{\rho_{w}}](https://tex.z-dn.net/?f=S.G%3D%5Cfrac%7B%5Crho_%7Bsw%7D%7D%7B%5Crho_%7Bw%7D%7D)
Here, density of sea water is
, surface gravity is S.G and density of water is
.
Substitute all the values in the above equation as follows:
![S.G=\frac{\rho_{sw}}{\rho_{w}}](https://tex.z-dn.net/?f=S.G%3D%5Cfrac%7B%5Crho_%7Bsw%7D%7D%7B%5Crho_%7Bw%7D%7D)
![1.025=\frac{\rho_{sw}}{1000}](https://tex.z-dn.net/?f=1.025%3D%5Cfrac%7B%5Crho_%7Bsw%7D%7D%7B1000%7D)
kg/m³.
Step2
Difference in pressure is calculated as follows:
![\bigtriangleup p=rho_{sw}gh](https://tex.z-dn.net/?f=%5Cbigtriangleup%20p%3Drho_%7Bsw%7Dgh)
![\bigtriangleup p=1025\times9.81\times320](https://tex.z-dn.net/?f=%5Cbigtriangleup%20p%3D1025%5Ctimes9.81%5Ctimes320)
pa.
Or
![\bigtriangleup p=(3217680pa)(\frac{1kpa}{100pa})](https://tex.z-dn.net/?f=%5Cbigtriangleup%20p%3D%283217680pa%29%28%5Cfrac%7B1kpa%7D%7B100pa%7D%29)
kpa.
Thus, the pressure difference across hatch of the submarine is 3217.68 kpa.
