The overhung crank of an engine having a cylinder diameter of 250 mm and stroke 400 mm. The connecting rod is 5 times the crank, the maximum explosion pressure in the cyl- inder is 1.7 MPa and engine runs at 200 r.p.m. Assuming a suitable stress for the material design the overhung crank. Also calculate the maximum stress in the crank arm when the crank is at 30° to the I.D.C position and the gas pressure is 0.8 MPa. Take modulus of sec- tion for rectangular section as 0.269 bt².
