Step 1 Calculate the resultant force at B

First we have to calculate the force on the member AB. We have

The horizontal force FH=ρAgx¯ =1000×9.81×6×2×(7+22)=941.76 kN ;The vertical force FV=1000×9.81×(π×22×6+6×7×2) =1563.7 kN ;So the net force is acting on AB is   =FH2+FV2=941.762+1563.72=1825.4 kN ;

The inclination of force on AB is = θAB=tan-1FVFH=tan-11825.4941.76= 62.7 °
