The connection between an electric motor and a construction machine shaft is provided by means of a rigid coupling with flanges, through which the moment is transferred via the coupling flanges. The power of the electric motor is 35kw and the speed is 870rpm. The coupling flanges are connected with three bolts of quality 5.6 with a placement diameter of 40 mm. The surface pressure safety stress for bolts is 16 MPa. The contact length of the bolt with the coupling flange is 12 mm. The coefficient of friction on the flange surfaces is 0.14; the operating factor for the coupling is 0.8. The working conditions of the contact element, the material properties are very well known; since force and stress analyses can be performed with high accuracy,; question) Determine the bolt that should be used in the clutch from the table.
