Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Rigid bar ABCD is supported by a smoth pin at D and by vertical aluminum alloy [E=10,000 ksi] bars attached at joints A and C. Bar (1) was fabricated to its intended length L1=40 in. Bar (2) was intended to have a length of 60 in.; however, its actual length after fabrication was found to be L2=59.88 in. To connect it to the pin at C on the rigid bar, bar (2) will need to be manually stretched by Δ=0.12 in. After bar (2) has been stretched and connected to the pin at C, a load P=20 kips is applied to the rigid bar at B. Use the following additional properties and dimensions: A1=A2=0.75 in2, a = 36 in, b =54 in, and c = 48 in.

A tensile-testing apparatus is to be constructed that must withstand a maximum load of 293516 N. The design calls for two cylindrical support posts, each of which is to support half of the maximum load. Furthermore, plain-carbon(1045) steel ground and polished shafting rounds are to be used; the minimum yield and tensile strengths of this alloy are 343 MPa and 565 MPa(82,000 psi), respectively. Specify a suitable diameter in mm for these support posts. Assume safety level is 2.3. Round your answer to 2 significant figures.
