PreviousAn 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?NextFor a two-cylinder locomotive with cranks at 90°: reciprocating mass per cylinder = 300 kg; crank radius = 0.3 m; driving wheel diameter = 1.8 m; distance between cylinder centre lines = 0.65 m; distance between driving wheel central planes = 1.55 m. Determine (i) the fraction of reciprocating masses to be balanced if hammer blow is not to exceed 46 kN at 96.5 km/h, (ii) variation in tractive effort, and (iii) maximum swaying couple.
