A mild steel member in a truss has a uniform cross-section of 200 mm X 100 mm. What would be the maximum permissible tensile force for the member if the material has a yield stress of 200 MPa and a factor of safety of 4 is used?

A mild steel rod is required to withstand a maximum tensile load of 250 kN with a factor of safety of 4. What will be a suitable diameter for the rod if the material has a tensile strength of 540 MPa?
