Answer:
The smallest radius at the junction between the cross section that can be used to transmit the torque is 0.167 inches.
Explanation:
Torsional shear stress is determined by the following expression:
Where:
- Torque, measured in .
- Radius of the cross section, measured in inches.
- Torsion module, measured in quartic inches.
- Torsional shear stress, measured in pounds per square inch.
The radius of the cross section and torsion module are, respectively:
Where is the diameter of the cross section, measured in inches.
Then, the shear stress formula is now expanded and simplified as a function of the cross section diameter:
In addition, diameter is cleared:
If and , then:
The smallest radius at the junction between the cross section that can be used to transmit the torque is 0.167 inches.

Answer:
The answer is "Choice b,c, and d".
Explanation:
The distillation would be the separation phase of working liquids that boil close to each other. Whenever the formulation is long-term, a much more fraction of a compound collected will have a lower boiling point than it would otherwise be. In other phrases, it'll be pulverized with both the lower level, also with the boiling point. Its structure of both the diluted volatile component may therefore include another cell's contaminants.
Answer:Crystallography is useful in phase identification. When performing any process on a material, it may be desired to find out what compounds and what phases are present in the material. Each phase has a characteristic arrangement of atoms.
Explanation:
Answer:
The external pressure is p = -21.9 psf or p = -8.85 psf
Explanation:
Given :
Velocity of wind, v = 120 mi / hr
(wind direction factor)
= topographical factor (for flat terrain)
= velocity pressure at height h
But for height h = 30 ft, = 0.98 (from table)
= 36.16
Now, , so (from table)
where, p = external pressure
G = 0.85 = gust factor (for typical rigid building)
(internal pressure co efficient)
Therefore putting the values,
p = -21.9 psf or p = -8.85 psf
