8- Problem:

A flanged coupling connects two transmission devices with pins of diameter 12 mm made of EN3 steel, at pitch circle diameter of 150 mm, If a torque of 2,600 Nm is applied with a required safety factor of 5, calculate the maximum number of studs pins required.



T = 2600 Nm

Material: EN3

SF = 5

D = 150 mm

d = 12 mm



 n (number of pins)



From Chart 9 for steel EN3
