Hi all, After a bit of help if possible. How do I go about calculating the horizontal reaction forces for points A and B on the attached pic. Again I am going to assume the principles of static equilibrium ∑ Fx = 0 ...∑ M = 0 I understand that all forces must 'balance' however, do I need to take into consideration all measurements etc? How do I go about that? Thanks for any help.

So once you get the location of exactly applied load, you can put the unknown horizontal reaction forces at A and B (namely Fa and Fb both pointing downwards). Then go ahead and write the two equilibrium equations. 1) Fx=0 that will give Fa+Fb+22kN = 0 2) M=0 take that at the point A. So itll be something like, Fb(0.4-0.1)-22kN(e)=0 e = distance between force 22kN and point A. from equation 2 you can find Fb= 22kN(e)/0.3 and this will be in kN. After finding Fb you can use equation number 1 to find Fa = -Fb-22kN and this will also be in kN. And there you have the two reactions.
