The cylinder of a four-stroke diesel engine has the following specifications: Brake power = 7.5 kW Speed=1400 rpm Indicated mean effective pressure = 0.35 MPa Mechanical efficiency = 80% Maximum gas pressure = 3.5 MPa The cylinder liner and head are made of grey cast iron FG 260 (Sut = 260 N/mm² and μ = 0.25). The studs are made of plain-carbon steel 40C8 (Syt 380 N/mm²). The factor of safety for all parts is 6. Calculate: = (i) bore and length of the cylinder liner (ii) thickness of the cylinder liner (iii) thickness of the cylinder head
