In any design of hydraulic structures, a safety factor should be
included. Describe what a safety factor is and why it is crucial in
the design. This question is open-ended. Therefore it must be
supported by relevant literature.
5. a) How is the factor of safety of a slope defined?
b) What is the general value of the factor of safety with
respect to strength for the design of stable slopes?
c) Compare the mass procedure and method of slices methods of
slope stability analysis.
Pavement performance is an important factor in pavement design
because it provides a framework upon which a judgement on the road
is either success or failure, which is associated with the ability
of the pavement to carry out the design loading. Based on these
statements, briefly discuss a distinction between the two different
types of failures.
How do you calculate the factor of safety for a worm in a worm
gear drive? I am looking for the mathematical equations to
calculate this. Linking outside resources would be much
appreciated.
PROJECT
4 : DESIGN A HYDRAULIC MOBILE CRANE
REQUIREMENTS:
•Design the system to carry load of up to 5000 lb
•Use a hydraulic winch(rotary actuator)to move the pulleys up
and down
•Use fail-safe measures to support positive loads and run-away
issues
•The speed of the crane shouldbe changeable
•Use dampeners to prevent vibration and maintain pressure and
flow where necessar
A hydraulic press for compacting powdered samples has a large
cylinder which is
10.0 cm in diameter, and a small cylinder with a
diameter of 2.0 cm. A lever is attached
to the small cylinder as shown in (Figure 1) . The sample, which is
placed on the large cylinder, has an area of 4.0 cm2.
What is the pressure on the sample if
F = 320N
is applied to the lever?
Express your answer to two
significant figures and...
I have a 6,000 lb truck. If I have a 4” hydraulic cylinder and
want the truck to raise 6ft in 3 seconds, what size drive motor and
pump do I need?The prime mover should spin at 1800 rpm.

from QFD, what factor use to determine most important design
specification?
Is it the absolute weight or relative weight? How can I list the
order of importance of the design specification using data from
QFD?
