Q4: a) Determine the valve lift & valve dimensions of an engine from the following data: Bore 140 mm; Stroke = 270 mm; Power = 8.25 kW; Speed = 475 r.p.m.; Maximum gas pressure = 3.5 N/mm²; the mean velocity of the gas through the port (VP) is 40 m/s. The safe stress in bending for the valve material is 56 MPa. The valve is made of steel for which k = 0.42. The angle at which the valve disc seat is tapered is 45°. Take the permissible bending stress =56MPa. Any other data required for the design may be assumed
