1.5 (A). A simple turnbuckle arrangement is constructed from a 40 mm outside diameter tube threaded internallyat each end to take two rods of 25 mm outside diameter with threaded ends. What will be the nominal stresses set upin the tube and the rods, ignoring thread depth, when the turnbuckle carries an axial load of 30 kN? Assuming asufficient strength of thread, what maximum load can be transmitted by the turnbuckle if the maximum stress islimited to 180 MN/m²?[39.2, 61.1 MN/m², 88.4 kN.]

Problem 2: A shaft is to be fitted with a flanged coupling having 6 bolts on a circle of diameter 150 mm and 4 bolts on a circle of diameter 100 mm. The shaft may be subjected to either a direct tensile load of 400 kN or a twisting moment of 18 kN-m. If the maximum direct tensile and shearing stresses permissible in the bolt material are 125 MPa and 55 MPa respectively. Find the minimum diameter of the bolt required. Assume that each bolt takes an equal share of the load or torque. Outer bolt Shaft circle Shaft Bolt Inner bolt Flange circle
