A coal conveyor belt is 900 mm wide and travels at 2.2 m/s. There are plans to build a surge bin to hold enough coal for two days production. Calculate the bin capacity required if thr bin is intended to hold coal produced in two eight-hour shifts. State any assumptions that you may make.

. (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)
