In the test assembly, it is desirable to measure the maximum power of the turboprop engine. Driven by a single-stage turbine through the gearbox, the propeller of the engine was measured to rotate at 2000 RPM. The gear box to which the propeller is connected consists of 3 stages. The cycle ratio of each stage is 2, 1.5 and 4, respectively. Calculate the turbine speed and turbine power, since the allowed torque limit for the turbine is set at 5 kNm.

In a six cylinder in-line two-stroke cycle Diesel engine, the cylinders are pitched 150 mm apart. The crank length is 100 mm and the ratio of connecting rod to crank is 4.5. The reciprocating mass per line is 1 kg. The engine speed is 2121 rpm. Two possible firing order for this engine are 1-5-3-6-2-4 and 1-4-5-2-3-6. As a young engineer, you have been tasked to evaluate the most suitable firing order for this engine. Your evaluation should include examination of the engine for balance of primary and secondary forces and couples for the given firing order. Apart from examining the engine, you need to justify why one firing order is superior to the other.
