Figure Q3 shows a symmetrically loaded beam, loaded at the leftmost position A (x=0m) with 20kN and rightmost position D (to be calculated) with 20kN. There is also a UDL of 10kN/m located in the middle of the beam spanning from position B to position C, see Figure Q3 for the start and end positions. The Y length spans for 1.7m and the Z length spans for 2.3m. There are two reaction forces of RA at position A and a further reaction force of RD at position D (to be calculated). Calculate the Shear Force value (using the sign convention given to you in the module's formula book) at a position of X=2.5m. State your answer in kilo-Newtons to one decimal place.
