A stainless-steel rod (AISI 304) of length ? = 100[??] and triangular cross-section is attached between two isothermal heat sinks at ?0 = 50℃. The rod perimeter is ? = 5[??]. When an unknown fluid at ?0 = 23℃ is in cross-flow over the rod, the temperature of the rod is midway between its two ends is measured to be ???? = 25℃. Determine the value of the convection heat transfer coefficient and the rate of heat loss from the rod.

In a manufacturing process, stainless steel cylinders (AISI 304)
initially at 600K are quenched by submersion in an oil bath
maintained at 300K with h=500W/m2-K. Each cylinder is of
length 2L=60 mm and diameter D=80mm. Consider a time 3 min into the
cooling process and determine the temperatures at the center of the
cylinder, at the center of the circular face and at the mid height
of the site. (Use the Heisler charts to answer these questions).

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withdrawn from the bath?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...

Attached to each end of a thin steel rod of length 1.10 m and
mass 6.60 kg is a small ball of mass 1.07 kg. The rod is
constrained to rotate in a horizontal plane about a vertical axis
through its midpoint. At a certain instant, it is rotating at 39.0
rev/s. Because of friction, it slows to a stop in 32.0 s. Assuming
a constant retarding torque due to friction, find the
following.
A) Angular Acceleration
rad/sec^2
B) Retarding...

A stainless steel (AISI 316) tube used to transport a
chilled pharmaceutical has an inner diameter of 30 mm and a wall
thickness of 3 mm. The pharmaceutical and ambient air are at
temperatures of 6oC and 23oC, respectively, while the corresponding
inner and outer convection coefficients are 400 W/m2 K and 6 W/m2
K, respectively.

A steel wire with a cross-section area 2.5X10^-3 m2 and a length
of 10 m is used to pull a truck on the road. The truck is 10 tons
and the friction coefficient between the tires and road is
0.25N/kg. Steel has a Young’s modulus 250MPa.
Suppose this wire contain surface cracks. Determine the largest
linear size of the surface crack so that the wire will not fail due
to fracture in this application. Kc = 0.1 MPa m^0.5

2) A steel rod with a cross-sectional area of 0.25 sq. in. is
stretched between two fixed points. The tensile load at 70 degrees
F is 1200 lb. What will be the stress at 0 degrees F? At what
temperature will the stress be zero?
Assume ? = 6.5 x 10-6 °F-1 and E = 30 x
106 psi.
