As a mechanical design engineer, you are assigned to evaluate a stepped rotating shaft that will be designed based on fatigue analyses for a heavy duty. The shaft is simply supported at two bearings A and E as shown in Figure 1 and subjected to completely reversed loads $P_i$ and $W_i$ as shown in Table 1: Table 1: i $P_i$ (N) $W_i$ (N) Cycles (in service) 1 12000 4000 500 2 8000 6000 800 3 4000 8000 1200 The above duty is to be repeated 400 times during the service. The notch sensitivity factor q at the fillet may be taken as 0.8. The reliability data is taken to be 90%. The shaft is forged from plain carbon steel ($S_{ut}$ = 300 MPa; S yield = 180 MPa). Evaluate whether or not failure will occur. Use the finite life estimation and cumulative fatigue damage theorem (Palmgren and Miner's Theory).

Q1. An AC circuit shown in Figure Q1 consists of two resistors, an inductor and a capacitor. The current source is given as $i_s(t) = 2 \cos(314t + 10^\circ)$ A. i. Find the reactance of the inductor, $jX_L$ and capacitor, $jX_C$. [2 marks] ii. Find voltage across inductor, $v_L(t)$ and voltage across current source, $v_s(t)$ using basic laws. [9 marks] iii. State whether the current source, $i_s(t)$ is 'lagging' or 'leading' the voltage, $v_s(t)$. [1 mark] 0.2 H 40 ? - $v_L(t)$ + + 80 ? $v_s(t)$ ? $i_s(t)$ -12 µF Figure Q1
