We Will Choose An Iron Based Material
average tensile 50 Mpa (material
We will calculate Sigma D, Re, Rm, Stress Amplitude and Maximum Stress.
How much tensile amplitude can the haight diagram max tensile

(I need the table and values ​​in any sample that I will determine myself. values ​​can be matched.)

(can be ready example just back down to 50Mpa)

An in-line, six-cylinder, 6.6-liter, four-stroke cycle SI engine with multipoint port fuel injection operates át 3000 RPM, with a volumetric efficiency of 89% and AF of 15:1. The engine has bore and stroke'related by S = 0.90 B. The engine has an exhaust pipe between engine and catalytic converter that can be approximated as a round pipe, 1.5 m long and 6.5 cm inside diameter. Exhaust temperature leaving the engine is 477°C, and the average wall temperature of the exhaust pipe is 227°C. Calculate the exhaust temperature entering catalytic converter [°C].

Water is flowing in a compressor steadily at 20 kPa and 40 oC to 1.7 MPa and 500 oC. The power input to the compressor is determined to be 5 MW. The water enters the compressor at a height of 5 m and leaves at 10 m of height. The velocities of the water coming in and out of the compressor are 50 m/s and 180 m/s respectively. a) Determine the work input per unit mass for the water flowing through the compressor. b) Calculate required mass of flow rate of the water.

A steam power plant operates on an ideal regenerative Rankine cycle. Steam enters the turbine at 6 MPa and 450oC and is condensed in the condenser at 20 kPa. Steam is extracted from the turbine at 0.4 MPa to heat the feedwater in an open feedwater heater. Water leaves the feedwater heater as a saturated liquid. Show the cycle on a T-s diagram and determine the fraction of steam extracted from the turbine for the open feedwater heater.
