Answer:
The Estimated uncertainty in a nominal displacement of 2 cm at the design stage is plus or minus 0.0124cm
Explanation:
uncertainty in a nominal displacement
= (u^2 + v^2)^(1/2)
assume from specifications that k = 5v/5cm
= 1v/cm
u^2 = (0.0025*2)^(2) + (0.005*10*2)^2 + (0.0025*2)^2
= 0.01225v
v = 2v * 0.001
= 0.002v
uncertainty in a nominal displacement
= (u^2 + v^2)^(1/2)
= ((0.01225)^2 + (0.002)^2)^(1/2)
= 0.0124 cm
Therefore, The Estimated uncertainty in a nominal displacement of 2 cm at the design stage is plus or minus 0.0124cm
Answer: Type the correct answer in the box. Spell all words correctly.
Which design principle indicates disparity between adjacent parts of a design to give it a striking overall look?
-blank- is disparity between adjacent parts of a design to give it a striking overall look.

Explanation:
it is very wide as you can see *also in french*
Answer:
Correct option is A - O(x)
Explanation:
Given f(x) = 10 and g(x) = x
Hence f(x) is O g(x)
As such correct answer is O(x) which is option A
Answer (Part 1):
620 joules
Explanation:
Work is done when force is applied on an object over a distance. It is measured in joules.
<u>Formula</u>
Thus, Work = Force x distance
Since, Work = ? (unknown value)
<u>Given:</u>
Force = 200N
Distance = 1.2 meters
<u>So,</u>
Work = 200N x 3.1 meters
= 620 joules
Thus, Amanda did a work of 620 joules on the crate.
Answer (Part 2):
240.25 joules
Explanation:
Work is done when force is applied on an object over a distance. It is measured in joules.
<u>Formula</u>
Thus, Work = Force x distance
Since, Work = ? (unknown value)
<u>Given:</u>
Force = 77.5N
Distance = 3.1 meters
<u>So,</u>
Work = 77.5N x 3.1 meters
= 240.25 joules
Thus, Amanda did a work of 240.25 joules on the crate.
Hope this helps! :)
