take initial hardness readings on each of three specimens(carbon steel, 1.5 to 2 inches wide, 3/16 inch thick, minimum 3 inches long). Test a series ofpositions at 1/8” intervals from the end to be worked into a chisel. Assuming readings seemconsistent, you may stop after 3 readings each.Part B –Two Hot-Worked Chisels (“A” – Air Cooled, “Q” – Quenched) 1. Heat one end of each piece until orange in color (≈1800 to 2000ºF), as depicted in Figure 1A. 2. Work the chisel edge into the specimens by hammering them at the anvil. Hold the cool end with pliers and hammer the heated end flat. While hammering, rotate the plates so that each side is flattened. Figure 1A

Therefore, we could calculate the overall efficiency of the gear pump.

There are three programming environments which can work with a VEX microcontrollersystem. These are the Easy C, ROBOT C, and MP Lab Development System.

plastic is injectedinto the mold. After 10 minutes the average temperature of the plastic is within the parameters for being injected,but the extra time is to help make the flow smoother which creates a better final product.To find the heat flux, the amount of heat that can be passed through the material can be computed using Fourier’sLaw using Q as heat flux, k as the material conductivity, and T as the temperature: 𝑑𝑑𝑑𝑑 𝑄𝑄 = −𝑘𝑘 𝑑𝑑𝑑𝑑The CFD program uses the nodes to find the (x,y,x) coordinates needed for the formula of
