During an engine test on the ground, a propeller thrust T = 2594 N is generated on the 2427 kg aeroplane with a mass centre at G. The main wheels at B are locked and do not skid; the small tail wheel at A has no brake. T 12° 1.4 m B 0.8 4 m m (a) Calculate the normal force at the wheel at A when the engine is switched off. Answer: (b) Calculate the normal force at the wheel at B when the engine is switched on. Answer: (c) Calculate the percentage change in the normal force when the engine is switched on. Do not include the percent sign in your answer. Answer:
