A jet engine that operates on Brayton cycle is at an altitud

A jet engine that operates on Brayton cycle is at an altitude (30,000 ft) where the engine entrance temperature is 228 K and the pressure is 30.8 kPa. We also know that the engine compressor pressure ratio is rp = 10 and the fuel to air mass flowrate ratio is 0.03. If the aircraft is moving at a velocity of 305 m/s and uses fuel with LHV= 44,102 kJ/kg calculate the engine exhaust velocity. (Note that cp = 1.0035 kJ / kg.K).

Solution

Two 3 kg uniform semicircular plates are attached by pins to the 2 kg uniform sleder rod AB. Assume that the plates roll without slip on the level ground.  Rod AB is displaced 10mm to the right and given a velocity of 5mm/s to the right

Q: Determine the period of small oscillations of the system. Rod AB is displaced 10mm to the right and given a velocity of 5mm/s to the right
