(2) Figure Q2 shows a 10 m long beam which has a concentrated load of X=95 KN located at the position A on the beam (x=0 m) as well as another load Z=42 kN at the end of the beam at
position E (x=10 m). There is also a Uniform Distributed Load (UDL) of loading Y=84 kN/m which starts at position C (x=5 m) and ends at position D (x=7 m). There are two reaction pivots:
- a left one located at B (x=3 m) and a right pivot located at D (x=7 m).
Calculate the reaction force RD experienced by the pivot at the position D in terms of kilo-Newtons to 1 decimal place.
