Question
An 8 m long I-beam made of mild steel is used to support an overhead crane in a workshop, as shown in Figure 2(a). Figure 2(b) gives the dimensions of the I-beam. When answering the following questions, include the weight of the beam in your calculations.
At what horizontal position on the beam would the load cause the maximum bending moment?
What is the minimum load that can initiate plastic deformation on the beam? What will be its location on the beam?
For the mild steel, take the elastic modulus as 210 GPa, yield stress as 350 MPa, and density as 7850 kg m−
