    Force at point A and E (Static Equilibrium)

    first draw free body diagram and find angle and stuff so at point A 9(Fna sin 19.47)=4(mg cos 70.53) + 4.5(Fb cos 19.47) 9(Fna sin 19.47)=875.4 N + 2785.74 N Fna=1220.38 N but I'm not sure.the other calculation is pretty much the same but with different angle and get 129.6 N so what did you...

    Force at point A and E (Static Equilibrium)

    yes with bar in the middle. I get 1220.38 N at point A and 928.58 N at point E.I also tried other calculation which i get 129.6 N at point A

    Force at point A and E (Static Equilibrium)

    a man is trying to fix the light bulb at the top of his house ceiling.to reach the bulb,he is using a stepladder that is in equilibrium state.sides AC and CE are each 9.0 m long and hinged at C.Bar BD is attached with a rod that is 3.0 m long,halfway up.The man who is climbing 5.0 m along the...
