Cornelsen focus on physics solutions
-548.08 is the answer to your question.. Good luck :)
The Poisson's ratio definition is given as the change in lateral deformation over longitudinal deformation. Mathematically it could be expressed like this,
Replacing with our values we would have to,
Therefore Poisson's ratio is 0.1977.
a). Frequency = (4,000 rev/minute)·(1 minute/60 sec) = <em>66 and 2/3 rev/sec</em>
b). Period = 1 / frequency
Period = 1 / (66-2/3 rev/sec)
Period = 1/66-2/3 sec/rev
<em>Period = 0.015 sec/rev </em>
Velocity is the speed of something in a given direction
