Design of Machine ElementsA shaft running at 400 rpm transmits 10 kW. Assuming allowable shear stress in the shaft as 40 MPa, find the diameter of the shaft.20267mDesign of Machine Elements(a) A solid shaft transmits a torque T. The allowable shear stress is \tau. The diameter of the shaft is (i) \sqrt[3]{\frac{16T}{\pi\tau}} (ii) \sqrt[3]{\frac{32T}{\pi\tau}} (iii) \sqrt[3]{\frac{64T}{\pi\tau}} (iv) \sqrt[3]{\frac{16T}{\tau}}20262mDynamics of MachineryAn aeroplane makes a complete half circle of 50 metres radius towards left when flying at 200 km/h. The rotary engine and propeller have a mass of 400 kg with radius of gyration 300 mm. The engine runs at 2400 r.p.m. clockwise when viewed from the rear. Find the gyroscopic couple on the aircraft and state its effect. What is the effect if the aeroplane turns right instead?20267mDynamics of MachineryThe turning moment diagram for a petrol engine is drawn to these scales: turning moment, 1 mm = 5 N·m; crank angle, 1 mm = 1°. The diagram repeats itself at every half revolution of the engine. The areas above and below the mean turning moment line taken in turn are 295, 685, 40, 340, 960, 270 mm². The rotating parts are equivalent to a mass of 36 kg at a radius of gyration of 150 mm. Determine the coefficient of fluctuation of speed when the engine runs at 1800 r.p.m.20267m
