Answer:
True
Explanation:
A semicircular or circular torch movement should be used when depositing weld beads.
Answer:
Both Technician A and B are correct
Explanation:
Due to a contamination of the clutch disc friction surface, the clutch chatters
The contamination that causes clutch chattering includes
1) Worn or broken motor mounts
2) Bell housing bolts becoming loose
3) Clutch link damage
4) Warped flywheel, due to overheating, the flywheel can become warped such that the non uniform surface interfaces the clutch resulting in clutch chattering
5) Engine or transmission oil contaminating the disc.
Answer:
275 MPa
Explanation:
Regardless of what it is holding, the stiffness of a bolt depends on its own material properties and geometry.
The stiffness is:
![k = E * \frac{A}{l}](https://tex.z-dn.net/?f=k%20%3D%20E%20%2A%20%5Cfrac%7BA%7D%7Bl%7D)
I assume this one is made of steel, because regular bolts are steel.
The Young's modulus for steel is E = 210 GPa
The longitude is given. (But note that in a real application you have to consider the length up to the nut.)
The section is (using the nominal diameter of 10 mm)
![A = \frac{\pi * d^2}{4} = \frac{\pi * 0.01^2}{4} = 7.85e-5 m^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B%5Cpi%20%2A%20d%5E2%7D%7B4%7D%20%3D%20%5Cfrac%7B%5Cpi%20%2A%200.01%5E2%7D%7B4%7D%20%3D%207.85e-5%20m%5E2)
Then:
![k = 2.1e11 * \frac{7.85e-5}{0.06} = 275e6 Pa = 275 MPa](https://tex.z-dn.net/?f=k%20%20%3D%202.1e11%20%2A%20%5Cfrac%7B7.85e-5%7D%7B0.06%7D%20%3D%20275e6%20Pa%20%3D%20275%20MPa)
