. (Grinding Operations and Grinding Machines) (USCS units) In a centerless grinding operation, the grinding wheel diameter = 8 in, and the regulating wheel diameter = 5.0 in. The grinding wheel rotates at 1500 rev/min, and the regulating wheel rotates at 180 rev/min. The inclination angle of the regulating wheel = 2.3°. Determine the production rate of cylindrical work parts whose diameter = 0.5 in and length = 5.0 in. Solutions used; fr = TD₂N, sin I

A 647-lb force is applied to a rotating tool steel bar at a frequency of 3000 cycles/minute. The bar has a diameter of 1.000 in. and is 12.00 in. long. The fatigue curve for the steel used in the bar is shown below. Calculate the time in minutes to 32FL failure given ±o = 120 110 100 90 80 70 60 50 40 30 20 10 1.00E+04 1.00E+05 1.00E+06 1.00E+07 1.00E+08 Number of cycles Applied Stress (ksi)

Question: A cylindrical rod of 1040 steel originally 11.4 mm (0.45 in.) in diameter is to be cold worked by drawing;  the circular cross section will be maintained during deformation.  A cold-worked tensile strength in excess of 825 MPa (120,000 psi) and a ductility of at least 12%EL are desired.  Furthermore, the final diameter must be 8.9 mm (0.35 in.).  Explain how this may be accomplished.

Kneading kneads 50 kg of dough 25 C with a mixing motor at 0.75 KW for 20 minutes. At this distance, heat equal to 300 j is expelled from the dough container. If the heat capacity of the dough is 0.8.C, calculate the final kj jg temperature of the dough.
