- An annealed aluminum alloy slab with a thickness of 12 mm and width of 1m is to be cold rolled to a thickness of 9 mm using 2-high rolls with roll diameter of 1m. The rolls have a coefficient of friction of 0.08 and they are rotating with a speed of 18 RPM. The aluminum has an entrance speed of 50 m/min and a width that does not change as a result of drawing. The strength coefficient K =240 and strain hardening exponent n =0.15. Please answer the following:
- Is the proposed reduction possible?
- Calculate the rolling forward slip.
- Calculate the rolling force (N).
- Find the total power (W) consumed by the process.

- Aluminum and Steel Samples
Dog-bone shaped samples Thickness = .003 inches; Width = 4 mm;
Length = 8 cm
- Polycarbonate Plastic Samples
Dog-bone shaped samples Thickness = .015 inches; Width = 4 mm;
Length = 8 cm
- iPod Wire Diameter = 1.2 mm for “thin”; Diameter = 2.0mm for
“thick”; Length = 7 cm for both
Calculate the stress (Force/Area) and strain (Elongation/Length)
for all samples.

The sample measurements for Aluminum, Copper and Nylon
have the same length, width, and thickness. While the length is
76.5mm and the width is 19.5mm, the thickness of these samples are
about 0.127 mm.
How might these specimens behave differently if they were
thick?

A turbine blade of solution annealed INCOLOY alloy 800 is 18 in
long and operates at 1400 degrees Fahrenheit. If the tip clearance
is 0.2 in and centrifugal forces induce an average longitudinal
stress of 10 ksi. After how many hours is expected the blade to
interfere with the turbine stator due to creep?

a rectangular slab of 2024-T6 alluminium alloy is to be machined
by a cutting tool of a rake angle of 6.5 degrees. the friction
coefficiet between the tool and the slabmaterial was found to be
0.32 . if the shear yield stress of the alluminium alloy is 210
MN/m^2 , calculate the force in the direction of the tool feed (Fx)
for a depth cut (t) of 0.8 mm and a unit tool width of 1mm.
