The drive shaft of the motor is made of a material having an allowable shear stress of τallow= 72 MPa. the shaft is operating at an angular velocity of 1700 rev/min. Take ci= 0.75 co. A) If the motor is to deliver a power of 25 kW, determine the required minimum outer diameter of the tubular shaft to the nearest mm. B)Determine the required corresponding inner diameter of the tubular shaft to the nearest mm.

2. An implant is made of a titanium alloy having an allowable shear stress of tallow = 50 MPa. If the diameter of the implant is 120 mm, determine the maximum torque T that can be transmitted. What would be the maximum torque T' if an 80-mm-diameter hole were bored through the implant? 1S T (Answer: T =16.96 kN.m; T'=13.613 kN.m)

Rev Part A The shaft is supported by a smooth thrust bearing at A and a smooth journal bearing at B. (Figure 1) If P = 20 kN , determine the absolute maximum shear stress in the shaft.

Figure 1 is presented the solid shaft AB rotates at 650 rpm and transmits 30 kW from the motor machine tools connected to gears F and G. Assuming that, 10 kW is taken off at gear F and 20 k taken off at gear G, knowing that allowable torsional shear stress is equal to (65 plus last digit of student ID) MPa. Design the smallest permissible diameter of shaft AB. Figure 1 150 mm 225 mm 905 mm 150 mm 60 mm 100 mm D. 60 mm B.

Part A The solid shaft cross-sections shown are subjected to the externally applied torques shown. Compare the corresponding shear stresses developed in each shaft at point P. P P 2 T Rank the solid shafts from the largest shear stress at P to the smallest shear stress at P. (For example, 4> 3 = 1 > 2). 0.5 T

Q2(c) The steel alloy shaft having a diameter of 38 mm is used to transmit torque, T as shown in Figure Q2(c). If the allowable shear stress of the shaft is 80kPa, i)Determine the maximum torque T that can be transmitted by the shaft. ii)What would be the maximum torque T' if a 25 mm diameter hole is bored through the shaft?
