Answer:
Step 1 of 3
Case A:
AISI 1018 CD steel,
Fillet radius at wall=0.1 in,
Diameter of bar
From table deterministic ASTM minimum tensile and yield strengths for some hot rolled and cold drawn steels for 1018 CD steel
Tensile strength
Yield strength
The cross section at A experiences maximum bending moment at wall and constant torsion throughout the length. Due to reasonably high length to diameter ratio transverse shear will be very small compared to bending and torsion.
At the critical stress elements on the top and bottom surfaces transverse shear is zero

Answer: D
Explanation: When you change your transmission fluid you change your filter. When you do that you clean where the filter was. Then you can put the new filter on and the new fluid.

Answer:
a) 
, b) 
The real force has the opposite direction.
Explanation:
a) Let assume that train moves on the horizontal ground. An equation for the distance travelled by the train is modelled after the Principle of Energy Conservation and Work-Energy Theorem:
![d = \frac{(51000\,kg)\cdot [(90\,\frac{km}{h} )\cdot (\frac{1000\,m}{1\,km} )\cdot (\frac{1\,h}{3600\,s} )]^{2}}{2\cdot (82000\,N)}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B%2851000%5C%2Ckg%29%5Ccdot%20%5B%2890%5C%2C%5Cfrac%7Bkm%7D%7Bh%7D%20%29%5Ccdot%20%28%5Cfrac%7B1000%5C%2Cm%7D%7B1%5C%2Ckm%7D%20%29%5Ccdot%20%28%5Cfrac%7B1%5C%2Ch%7D%7B3600%5C%2Cs%7D%20%29%5D%5E%7B2%7D%7D%7B2%5Ccdot%20%2882000%5C%2CN%29%7D)
b) The acceleration experimented by both trains are:
![a = -\frac{[(90\,\frac{km}{h} )\cdot (\frac{1000\,m}{1\,km} )\cdot (\frac{1\,h}{3600\,s})]^{2}}{2\cdot (194.360\,m)}](https://tex.z-dn.net/?f=a%20%3D%20-%5Cfrac%7B%5B%2890%5C%2C%5Cfrac%7Bkm%7D%7Bh%7D%20%29%5Ccdot%20%28%5Cfrac%7B1000%5C%2Cm%7D%7B1%5C%2Ckm%7D%20%29%5Ccdot%20%28%5Cfrac%7B1%5C%2Ch%7D%7B3600%5C%2Cs%7D%29%5D%5E%7B2%7D%7D%7B2%5Ccdot%20%28194.360%5C%2Cm%29%7D)
The coupling force in the car A can derived of the following equation of equilibrium:
The coupling force between cars is:
The real force has the opposite direction.
