An aeroplane makes a complete half circle of \(60 \mathrm{~m}\) radius towards the left when flying at \(180 \mathrm{~km} / \mathrm{h}\). The rotary engine and the propeller of the plane have a mass of \(35 \mathrm{~kg}\) with radius of gyration of \(0.25 \mathrm{~m}\). The engine runs at \(2400 \mathrm{rpm} \mathrm{cw}\), when viewed from the rear. Find the gyroscopic couple on the plane and state its effect on it. What will be the effect if the aeroplane turns to its right instead of the left?
