Figure Q12 shows a 4m long beam split into 4 equal sections. The beam is loaded at the leftmost position at A, with a load 30.3 kN and a load of 102.5 kN at B where there is also a left pivot. The beam also contains a right pivot at D. There is a third unknown load X kN located at the rightmost position at E. Calculate what is the maximum load X (in terms of kilo-Newtons), you can apply without causing the beam to topple*. * You are required to find the largest possible value of X so that the structure will remain in static equilibrium, assuming that pivots cannot support negative reactions. Select your answer using the nearest whole number. 30.3 kN A 1m 102.5 KN B 2m D 1m X KN E
