Chapter 3, Problem 3.2P

High-strength steel is required for use in building structures and equipment (e.g., cranes). It is produced by heat treating quench-hardened steel in a process called tempering that reduces brittleness and imparts toughness. In a production facility, alloy steel plates ( k = 50 W/m K, c = 460 J/kg K, and ρ = 7865 kg/m3) of thickness 3.0 cm have to be tempered in a convective oven by heating them to 550°C. If the plates are initially at 40°C and the air inside the heat treating oven is at 700°C with a convective heat transfer coefficient of 45 W/m2 K, determine how long the plate has to remain in the oven.

Problem 3: The inertia matrix can be written in dyadic form which is particularly useful when inertia information is required in various vector bases. On the next page is a right rectangular pyramid of total mass m. Note the location of point Q. (a) Determine the inertia dyadic for the pyramid P, relative to point Q, i.e., 7%, for unit vectors ₁₁, 2, 3.
