Explain the modern control methods that controls the braking
force on each wheel showing
the advantages and disadvantages of those methods. Give examples
from commercial brands.
As a mechanical engineer, design a hydraulic circuit
with pushing and pulling force using a lever. Please consider a
minimal usage of components in your design. Explain the operation
based on directional control valve position. Use symbols in
accordance to ISO 1219.
A manufacturing machine supplier needs your help to
design a hydraulic circuit for 2 cylinder output that operate in
sequence, one after another. Please consider a minimal usage of
components in your design. Explain the operation based on...
a)Sketch the distribution curve showing the area in the tails
and the critical values.
b)Show any expressions that determine the confidence interval
(such as margin of error) with the numbers in place and calculate
the necessary value(s).
c)Write the confidence interval in the usual way (for example
4.34<p<5.68)
1)The number of non-native plants in a plot of 1 square meter is
determined for 28 randomly-selected plots. The sample has a mean of
8.50 plants and a standard deviation of 0.72...

2)The local transit authority analyzed the lateness of its
buses. After randomly sampling 29 bus arrival times it was found
that the amount of time the buses were late had a standard...
F is a position dependent force given by F(x) = -e^-x. Sketch
the graphs showing F(t), v(t), and x(t) for initial velocity of
10m/s, initial position of 100m, and mass = 1kg. Mention all
salient points.
Sketch and label a clamping circuit. Use a 2.5 V rms source and
an ideal diode. Explain how it works. Show the voltage wave forms
in a diagram, giving numeric values where appropriate.
Sketch the layout for a typical conventional wastewater
treatment plant. Label each process. Briefly describe pretreatment,
primary treatment, and secondary treatment and their basic
functions.
Sketch potential energy curves for the ground and excited states
showing events leading to phosphoresce. Use arrows to label all
necessary transitions and answer the following:
A) Based on your picture does phosphoresce occur at lower or
higher wavelength relative to the absorption wavelength?
B) Would you expect 0-0 transition for absorption and
phosphorescence to be coincident?
