1B. A simply supported beam of $355 strength steel is required to support a load (W) of 333 kN. The span of the beam (L) is 5.5m. You are asked to: i. Calculate the deflection of the beam in (mm). The deflection formula can be expressed by: 384 FI where E = 210,0000 N/mm' 1=11,700 cm" 1C. Solve the following simultaneous equations: 2x+y -5 and -yl= 3 1D. A formula for the velocity (V) of waves in shallow water is
