Answer:
158
Explanation:
The input is 6.185/10.000 = 0.6185 of the full-scale of the A/D converter. If a 10V input is represented by a register value of 255, then the expected register value for this input is about ...
0.6185·255 = 157.7175 ≈ 158
_____
In hexadecimal, that is 9E.
Answer:
The biggest expectation of an engineer when he tests out a new design is that he expects the product to not fail, and all the stress and strains does not exceed the failure criteria.
Explanation:
In engineering design, failure of materials is considered, and the designed is usually designed to not reach or exceed the failure region of its stress strain relationship. This is why factor of safety is usually determined for each material, and it serves as a guideline for the designing of new designs. This factor of safety is the value, below which the material properties is able to cope with design stress and strain, and above which failure is likely to occur.
Answer:
Value of Young's modulus is obtained as
Explanation:
We know from the basic stress strain relationship
Stress is obtained as
now the strain is obtained as
using these values in the above equation we obtain E as
Definitely test 2 because it will show if there is a chemical reaction of not
