If you were choosing between two strain gauges, one which has a single resistor in a bridge that varies and one that has two res
istors that vary, one that increases and one which decreases, which would you expect to give a more linear voltage output (that is, a linear function of ‘x’, the position of the potentiometer)?
1 answer:
Answer:
A strain gauge in which only one resistor varies is typically called a quarter bridge arrangement. The one in which 2 resistors vary, is called a half bridge arrangement, where the resistors showing opposite effects are mounted on either side of the flexing body. The figures and relationship between the output voltages and the change in resistance delta_R, is shown in the below diagram:

Answer:
The shaft work generated per kilogram is
Explanation:
Given:
Temperature K
Initial Pressure MPa
Final pressure MPa
From the table superheated,
and
Work done by shaft is,
But here efficiency is 0.56,
So work generated per kg is,
Work =
Work =
Therefore, the shaft work generated per kilogram is
Answer:
Attached below are the sketches
answer :
c) G(s) = 100 / ( s + 100 )
d) y'(t) + 100Y(s) = 100 X(s)
e) g(t) = e^-100t u(t)
Explanation:
a) Sketch the bode plot
The filter here is a low pass filter
b) Sketch the s-plane
attached below. pole ( s ) is at 100
c) write the transfer function of the filter
Transfer function ; G(s) = 100 / ( s + 100 )
d) write the differential equation
Y(s) / X(s) = 100 / s + 100
Y(s) [ s + 100 ] = 100 X(s)
= sY(s) + 100Y = 100 X(s)
∴ differential equation = y'(t) + 100Y(s) = 100 X(s)
e) write out the unforced transient response
g(t) = e^-100t u(t)
f) write out the frequency response
