A structure is designed as a horizontal cantilever beam, of circular cross-section, and length 1 m. One end is built into a wall and the other supports a load of 3 kN. Applying a safety factor of 2, what bar diameter is required to prevent surface yield- ing, if the material is: (a) mild steel of yield strength 225 MPa? (b) maraging steel of yield strength 2250 MPa?
