(3) Figure Q3 shows a symmetrically loaded beam, loaded with a single Uniform Distributed Load (UDL) starting from the leftmost position A (x = 0 m) ending at the end of the beam at therightmost position D. The UDL has loading case of 10 kN/m, see Figure Q3 for the start and end positions. There are two symmetrically located pivots causing reaction forces of RB at positionB (Y 1.4 m) and Rc at position C. The central section of the beam spans for 2.8 m.Calculate the Shear Force value (using the sign convention given to you in the module's formula book) at a position of X=1.7 m.State your answer in kilo-Newtons to one decimal place.UDL = 10 kN/mAYmBX = ?Zm+⭑CYmD
