  An intermediate shaft of a gearbox, supporting two spur gears A and B and mounted between two bearings C1 and C2, is shown in the below figure. The pitch circle diameters of gears A and B are 500 and 250 mm respectively. The shaft is made of alloy steel 20MnCr5. (\( S_{ut} = 620 \) and \( S_{yt} = 480 \) N/mm\(^2\)). The factors \( k_b \) and \( k_t \) of the ASME code are 2 and 1.5 respectively. The gears are keyed to the shaft. Determine the shaft diameter using the ASME code.

  Which of the following causal analog transfer functions is used to design causal IIR digital filter with transfer function? $$ H(z) = \frac{0.05z}{z-e^{-0.42}} + \frac{0.05z}{z-e^{-0.2}} $$ Assume impulse invariance transformation with \( T = 0.1 \, \text{s} \). 

  • \( H(S) = \frac{0.5}{S+4.2} + \frac{0.5}{S+2} \)
  • \( H(S) = \frac{0.5}{S+2.1} + \frac{0.5}{S+4} \)
  • \( H(S) = \frac{0.5}{S-2.1} + \frac{0.5}{S-4} \)
  • \( H(S) = \frac{0.5}{S-4.2} + \frac{0.5}{S-2} \)
