# 1- Answer the following as true (T) or false (F) (a) A second order sy.docx

1. Answer the following as true (T) or false (F) (a) A second order system generally contains a second derivative term in the model due to inertia. (b) A sinusoid input is the most common simple periodic input. (o) The capacitor in an RC circuit is an energy storage device, therefore the system is a (d) A Histogram is a graphic that describes the distribution of a finite or discrete pop (e) In the limit as the interval size (5) approaches zero a histogram becomes a econd ulation. Chi-Squared order distribution. ave enough data points a Linear Least Squares Regression can be used directly using a strain gage and a P3500 unit. (o A long as you have enough data points a Linear Least Sqvares Regression can be to fit a a higher order curve (g) Stress in a beam can be measured (h) A strain gage detects displacement through change in resistance, -
Solution
a) Flase, a second order system contains second derivative in the model due to the presence of 2 energy storage elements.
b) True, a sinusoid and cosinusoid are the most common simple periodic inputs.
c) Flase, as the given RC circuit contains only one energy storage element, it is first order only.
d) True, A histogram is a display of statistical information that uses rectangles to show the frequency of data items in successive numerical intervals of equal size.
g) True, stress in a beam can be found out by using the P3500
h) True, strain gauge employs this technique. when there is a strain, then there will be a change in electrical resistance.
