Question

b) 1.2mm at the free end. The beam has a point load of 5kN at the free and a UDL of 350N/m along its entire length. Calculate the minimum required diameters of a tube cross section if the outer diameter is twice the inner diameter (D 2d). Take the Young's modulus as 190GPa. A cantilever steel beam is 2.5m long and has a maximum deflection of

please show all working out as I have answered but got the wrong answer
Answer= inner diameter=113mm
                   outer diameter=226mm
