Question
A steel shaft 3 m long is transmitting 1 MW at 240 rev/min. The working conditions to be satisfied
by the shaft are: (a) the shaft must not twist more than 0.02 radian on a length of 10 diameters.
(b) the working stress must not exceed 60 MN/m2. If the modulus of rigidity of steel is 80 GN/m2.
what is: (i) the diameter of the shaft required.
(ii)the actual working stress. (iii) the angle of twist of the 3 m length.
[Ans: 150 mm; 60 MN/m2 ; 0.030 rad]

- A composite shaft shown, composed of a steel (G = 77 GPa) core inside an aluminum (G = 25 GPa) jacket, carries a torque, T = 10 kN-m. The shaft is designed such that the aluminum jacket will fail first upon the application of the torque.What must be the minimum shear strength of steel such that the aluminum jacket will fail first? (Please explain)arrow_forwardOnly HAndwritten answer pleasearrow_forward8.9 (A/B). A solid steel shaft of 200 mm diameter transmits 5 MW at 500 rev/min. It is proposed to alter the horsepower to 7 MW and the speed to 440 rev/min and to replace the solid shaft by a hollow shaft made of the same type of steel but having only 80% of the weight of the solid shaft. The length of both shafts is the same and the hollow shaft is to have the same maximum shear stress as the solid shaft. Find: (a) the ratio between the torque per unit angle of twist per metre for the two shafts; (b) the external and internal diameters for the hollow shaft.
