## identify which type or types of lowpass filter have the characteristic described.

Among Butterworth, Chebyshev Type 1, Chebyshev Type 2 and Elliptic filters, identify which type or types of lowpass filter have the characteristic described. (a) Magnitude frequency response in the passband monotonically approaches a slope of zero at zero frequency. (Monotonic means “always moving in thesame direction.” That is, always moving up or always moving down or “not rippling.”) (b) Magnitude frequency response in the stopband monotonically approaches zero as frequency approaches infinity. (c) Fastest transition from passband to stopband for a given filter order. (d) Slowest transition from passband to stopband for a given filter order.

### design suitable bearings to support the load for at least 5E8 cycles at 1 200 rpm using deepgroove ball bearings.

The shaft shown in Figure P11-4 was designed in Problem 10-19. For the data in row (a) of Table P11-1, and the corresponding diameter of shaft found in Problem 10-19,….

### Find the minimum film thickness for a long bearing with the following data: 30-mm dia, 130 mm long, 0.0015 clearance ratio, 1 500 rpm, ISO VG 100 oil at 200°F, and supporting a load of 7 kN.

1.       A paper machine processes rolls of paper having a density of 984 kg/m3. The paper roll is 1.50-m OD X 22-cm ID X 3.23-m long and is on a simply supported, 22-cm OD, steel….

### Find the minimum film thickness for a bearing with these data: 30-mm dia, 25 mm long, 0.0015 clearance ratio, 1 500 rpm, ON = 30, ISO VG 220 oil at 200°F.

1.       Problem 7-12 estimated the volume of adhesive wear to expect from a steel shaft of 40 mm dia rotating at 250 rpm for 10 years in a plain bronze….
