Three objects, cylindrical rod (radius = 0.1 m), steel ball (radius = 0.1 m) and flat screen (length = 0.1 m) with surface temperature of 65 ℃ are exposed in perpendicular direction to water flow at 30 m/s and 30 ℃. Assume the area of all three objects are the same as 1 m2 , determine the individual values of convective heat transfer coefficient for each object, and their respective heat loss.

A cylindrical rod 25.0 cm long with a mass of 1.20 kg and a
radius of 1.50 cm has a ball of diameter of 7.90 cm and a mass of
2.00 kg attached to one end. The arrangement is originally vertical
and stationary, with the ball at the top. The apparatus is free to
pivot about the bottom end of the rod.
(a) After it falls through 90°, what is its rotational kinetic
energy?

A steel rod 0.450 m long and an aluminum rod 0.250 m long, both
with the same diameter, are placed end to end between rigid
supports with no initial stress in the rods. The temperature of the
rods is now raised by 60.0 ∘C.
What is the stress in each rod? (Hint: The length of
the combined rod remains the same, but the lengths of the
individual rods do not.)

A cylindrical tube of mean radius 1” and wall thickness 0.1” is
subjected to an internal pressure p = 300 psi and a torque
T = 2000 lb-in. The ends of the tube are closed. Find the
safety factor against yielding if the material yields in uniaxial
tension at SY = 8 ksi and Von Mises theory is used.
