Did not engineer cables factoring wind shear
Answer:
The term Accuracy means that how close our result to the original result.
Suppose we do any experiment in laboratory and we calculate mass = 7 kg but answer is mass = 15 kg then our answer is not accurate.
And the term Precision means how likely we get result like this.
Suppose we do any experiment in laboratory and we calculate mass five times and each time we get mass = 7 kg then our answer is precised but not accurate.
Explanation:
As a general rule of thumb, the large the diameter of a bearing, bushing or pin, the larger the tolerance range,” Brieschke points out. “The inverse is true for smaller-diameter pieces.”
Mike Brieschke, vice president of sales at Aries Engineering, says a 0.25-inch-diameter metal dowel that is press-fit into a mild steel hole usually has an interference of ±0.0015 inch. Parts in noncritical assemblies tend to have looser tolerances

Answer:
The sound intensity is reduced by a factor of 1995.26
Explanation:
When comparing two sound intensities, the intensity level is measured in the unit of decibel or dB. The intensity of the threshold of hearing for a human being is 10^−12 W/m^2
. When the intensity level is zero, it means that the sound intensity is the same as the threshold of hearing.
The reduced sound intensity level is given as 33 dB, so
10 log (I/Io) = - 33
I : intensity of the sound
Io ( =
10^−12 W/m^2): threshold of hearing
So, the intensity ratio is
I/Io = 10^-3.3
= 5.01 x 10^-4
1/ 5.01 x 10^-4 = 1995.26
