Question

What would the reaction force for A and B in the x and y direction be ?

Answer 1

Each of the four segments is 3 m wide and 4 m high.

I found the x direction to be 3F it's just the Y i am having trouble with

Answer 2

@AllTehMaffs if you could quickly help with this it would be be highly appreciated ^.^

Answer 3

I'm not great at these problems (terrible, actually), but based on p. 4 of this (it's a pdf, sorry)

I think you're right about the forces in the x direction

\[ \sum F_x = Ax+B_x = 0 \quad \longrightarrow \quad A_x = -B_x\]
\[ \sum M_A = 4B_x + 12m (F)=0 \quad \longrightarrow \quad B_x = -3F\]

Then I think you can do junction analysis for A and B labeling like





So I think it's 3/4F , but I'm not at all sure
