Problem 1: The pin in a Box-Pin coupling is acted upon by a force (F), that varies as random variable due to misalignment as (2, 0.08) kN. The load act at a distance (/) that varies as (25 t 3) mm. The diameter of the pin (D) is 18 mm. The fillet radius at the pin shoulder is about 1.5 mm. The stress concentration factor due to fatique in bending is thus a random variable kb that could vary from 1.3 to 1.5. The pin is made of steel AISI 4340 with mean endurance strength in bending of 400 MPa, and a standard deviation of 25 MPa. Determine the pin diameter (d), if one pin in every 10000 may be permitted to fail.
