Develop a heat treatment plan for a 0.5 inch diameter part made
of H13 tool steel to be heat treated to a RC 50 to 52 and then
stress relieved. ( show steps please )
Develop a heat treatment plan foe a 2 inch diameter part made of
4140 to be heat treated to a Rockwell of 48 to 50 Rockwell C on the
surface. ( show steps please)
As part of a heat treatment process, cylindrical, 304 stainless
steel rods of 100-mm diameter are cooled from an initial
temperature of 500ºC by suspending them in an oil bath at 25ºC. If
a convection coefficient of 500 W/m2·K is maintained by
circulation of the oil, how long does it take for the centerline of
a rod to reach a temperature of 52ºC, at which point it is
withdrawn from the bath? If 9 rods of length 1 m are...
As part of a heat treatment process, cylindrical, 304 stainless
steel rods of 100 mm diameter are cooled from an initial
temperature of 500°C by suspending them in an oil bath at 30°C. If
a convection coefficient of 500 W/m2K is maintained by circulation
of the oil, how long does it take for the centerline of a rod to
reach a temperature of 50°C, at which point it is withdrawn from

You have a nominal 3-inch diameter steel pipe, 15 feet high that
is embedded into a concrete foundation. Neglecting the weight of
the column, answer the questions below:
A. What is the maximum vertical load this pipe can
support/critical load (#)?
B. If a vertical load of 2,000#s and a horizontal force of 100#s
are applied at the top of the column, what are the maximum combined
tensile and compressive stresses (psi) where the column meets its
foundation? Are they...

your mix design. (1 mark)
Problem 3 (36 Pts)
The steel pipe is 0.5 m long and has an internal diameter of 60
mm and an external diameter of 80 mm. The Young’s modulus E is 200
GPa and the Poisson ratio ν is 0.32. The pipe experiences a
twisting moment of 8 kNm and a bending moment of 3.5 kNm.
4p a) Sketch roughly how the angle of rotation and vertical
displacement change as a function of distance from the free end of
the...
In an industrial process, 20 mm diameter spherical steel ball
bearings are heat-treated to improve their durability. For
application (1), the entire ball bearing needs to be heated evenly
to 1000 K. For application (2), only the outer 1 mm of the ball is
to be heated to a temperature in excess of 1000 K. The properties
of the ball bearing are c = 0.5 kJ/kg*K; p = 7800
kg/m3; k = 50 W/m.K. At your facility, you have access...
Materials Engineering Question
Suggest the optimal heat treatment and condition for 0.45 wt.%
steel required, to produce what you consider to be the best
combination of properties for a “Chef’s Knife”. Explain your answer
and use any literature required to justify it.
“The schedule
management plan is created as a part of Develop Management Plan
process in Integration Management. A project manager must create a
schedule management plan and it is observed that in real-world
scenarios most of the project managers miss on this important
aspect. A schedule management plan should include the methodology
used to create the schedule. The schedule management plan should
also include the duration of each activity and the efforts required
for those activities. All of this should...
