A)
L = length of the rod = 60 cm = 0.60 m
P = rate of heat transfer = 180 J/s
Tf = temperature of furnace = 400 oC
Tw = temperature of water = 100 oC
k = thermal conductivity of steel = 50.2 W/mK
A = area of cross-section = ?
Rate of heat transfer is given as
P = k A (Tf - Tw )/L
180 = (50.2) A (400 - 100)/0.60
A = 7.17 x 10-3 m2
d = diameter
area is given as
A = (0.25) d2
7.17 x 10-3 = (0.25) (3.14) d2
d = 9.6 x 10-2 m
d = 9.6 cm

A cylindrical rod of 1040 steel having originally 11.4 mm in diameter is cold-worked by drawing (i.e. pulling through a die with a hole smaller than the original rod cross section). The circular cross section will be maintained during deformation. The deformed steel is desired to have tensile strength in excess of 825 MPa and ductility of at least 12% EL. The final diameter must be 8.9 mm. Explain how this may be accomplished.

Learning Goal: To use the principle of superposition to determine the total deflection in a cylindrical rod due to a static loading. A steel rod (E= 200 GPa) is subjected to the load shown, where P = 2800 kN. A gap a = 1.90 mm exists before the load is applied. The elongated rod contacts the top surface at C'.

Design the cooling system used to manufacture the leg of a table, shown in Fig.2. You will have to determine the required diameter D so that the leg can withstand 100 kg of axial loading. Once the diameter has been determined, you will need to determine the Revolutions per Minute (RPMs) of the fan needed to cool down the leg to 90-C in less than 2 minutes before it starts deforming after being 3D printed. Consider the leg of the...
