(c) Calculate from first principles, the general equation for the vertical deflection of the beam, in terms of the variables, P and L and El (Refer Figure 1) and the beam self-weight, w(kN/m). Find the location of and the corresponding maximum deflection equation for the beam, then calculate the corresponding numerical values for the deflections corresponding to the loads Py and P, in Section (a) above. Show all neat hand workings undertaken, with explanatory text to guide the reader.

For a section, the term "thickness' refers to the thickness of the part from which the sample is taken. 2. In the case of sheet piling, the minimum yield strength is 230 MPa for all thicknesses, for grade 250 only. 3. Sa is the original cross-sectional area of the test piece before testing.
