To determine the reactions at B and F, I don't know how to handle that L-shaped beam connected to the horizontal beam. My attempt is: $$\sum F_{y} \colon\;\;\; -200 + R_{B} - 75 + 32 + R_{F} - 1632 = 0$$ from which it follows that ##R_{B} + R_{F} = 1875##. $$\sum M_{B} \colon\;\;\; -5 \times...

Thank you very much for all your help.

OK. Now I get it. To find the height ##h_{0}##, do I have to write ##h_{1} = 5.74 - h_0##? Or maybe ##h_{0} < 5.74\, ft##?

I don't get it. Could you please explain me a little bit more? I was trying to follow the method used in standard textbooks.

I really need a help with this exercise: A ##1.75##-m-high container has two immiscible liquids stacked on top of each other. The upper liquid has specific gravity ##SG = 0.45## and the other has density ##\rho = 61.78\, lbf/ft^3##. If the pressure exerted by the lower liquid at the bottom is...
