Heat-Transfer. A steel ball of diameter 60 mm is initially in thermal equilibrium at 1030°C in a furnace. It is suddenly removed from the furnace and cooled in ambient air at 30°C, with convective heat transfer coefficient h = 20 W/m²K. The thermophysical properties of steel are: density ρ = 7800 kg/m², conductivity k = 40 W/mK and ...

The volume of the steel bar is the product of the area of the cross-section and the length: π x r 2 x l = 3.1416 x 10 2 x 1000 = 314,160 mm 3 = 314.16 cm 3 (r = 1/2 x diameter, l = 1 m = 1000 mm). If using a carbon steel with density of 7.95 g/cm 3, we need the product of 7.95 and 314.16, which equals 2497.572 g, or ~2.498 kg.

Shafts with four splines work with ball spline bearings, which create relatively little friction. They're commonly found in robotic and other automated systems that require complex, fast movements. They don't transmit as much torque as shafts with six splines. All four -spline shafts are 52100 alloy steel for high strength.
