A temperature measurement system shows the second order
dynamics whose output y(s) in 0C and input x(s) in
0C is related with the transfer
function
Gs=(xs) /
(ys)=(s2+8s+15)
/ 2
A step change of magnitude is introduced in this system.

#1 A mass measurement system behaves as a second-order system
(consisting of a mass = 50g, a spring, and a viscous damping
element). To determine the damping the ratio, the system was
exposed to a step input and decaying oscillating amplitude of the
system output was measured. Results of these measurements showed
that the damping ratio = 0.7 and the ringing frequency
fd =389 Hz. Calculate the following and report results
using 3 significant digits minimum:
The natural frequency, in...

For a general second order control
system. On a complex plane graph, with real and imaginary axes,
show the region where the roots of a stable second order control
system must lie in order to satisfy the following performance
conditions:
Settling time between 0.4 and 0.8 seconds
Peak overshoot below 5%
Frequency of oscillation below 8 rad/sec
What is the reaction order with respect to initiator
concentration (e.g. first order, second order, etc.) for each of
the following steps:
a. Initiation
b. Propagation
c. What is the relationship between initiator concentration and
critical chain length?
The reaction 2HI --> H2 + I2 is second
order in [HI] and second order overall. The rate constant of the
reaction at 700 degrees celsius is 1.57 x 10-5
M-1 s-1. Suppose you have a sample in which
the concentration of [HI] is 0.75 M. What was the concentration of
HI 8 hours earlier?
