Hot forging is used to reduce a metallic cylindrical workpiece
with a diameter of 12 cm and height of 24 cm to a height of 15 cm.
The coefficient of friction of the open die plate with the
workpiece is 0.18 and the process takes 4 seconds to complete and
at a constant speed. The strength coefficient of the workpiece C=
180 MPa and strain rate sensitivity exponent m = 0.25. calculate
the following:
The forging shape factor at the end of the process.
The maximum flow stress (MPa).
The maximum forging force (N).
The power (W) required to complete the process.

Calculate the forging force for a solid, cylindrical workpiece
made of annealed 1020 steel that is 3.5 in. high and 5 in. in
diameter and is to be reduced in height by 30%. Let the
coefficient of friction be 0.15 and ignore the effects of
barreling.
An open forging die used to forge a cylindrical part with the
initial diameter is 45 mm and the initial height is 40 mm. The
coefficient of friction at the die-work interface is 0.20. The
height after forging is 25 mm. The yield strength of the work
material is 285 MPa, and its flow curve is defined by a strength
coefficient of 600 MPa and a strain-hardening exponent of 0.12.
Determine the force in the operation (a) just as the...
A 12-cm tall, 6-cm outer diameter cylindrical ceramic mug filled
with tea is boiling in a microwave oven. Assume latent heat of
evaporation as 2260 kJ/kg. The convection heat transfer coefficient
is h=20 W/(m 2 K) and the air in the microwave is at 20 °C. The
mug’s wall thickness is 6 mm and the ceramic thermal conductivity
is 30 W/(mK). Neglect heat transfer from the bottom of the mug and
calculate the rate (in g/s) at which the tea...
A cylindrical glass tank with a diameter of 8.6 cm and a height
of 25 cm is inverted and inserted into another tank of water. If no
air is allowed to escape from the glass container when submerged,
what is the height of the air column in the glass tank when its
edge is 2.0 m below the surface of the water?
A cylindrical shaped potato with length 2 cm and a diameter of
0.5 cm was dried at a temperature of 65 o C in a convective oven

Question 1
a) A cylindrical feedstock of length = 35.4 cm and diameter = 10
cm is subjected to turning using a high speed steel tool. For this
tool, n and C values in the Taylor tool life equation are 0.125 and
70 m/min, respectively. The cost for hiring an operator and using
the machine tool are $82 per hour. The tooling cost per edge of
cutting is $5. Loading and unloading the part on to the machine
takes about...
A cylindrical soil sample, 7.3 cm in diameter and 16.8 cm in
height, is tested in a constant-head permeability apparatus. A
constant head of 75 cm is maintained during the test. After 1
minute of testing, a total of 945.7 gm of water was collected. The
temperature was 20 oC. The void ratio of the soil was 0.43.

A 1.60 m cylindrical rod of diameter 0.550 cm is connected to a
power supply that maintains a constant potential difference of 17.0
V across its ends, while an ammeter measures the current through
it. You observe that at room temperature (20.0 ∘ C ) the ammeter
reads 18.8 A , while at 92.0 ∘C it reads 17.3 A . You can ignore
any thermal expansion of the rod.
