    What is the tension required for the crosspiece in an A-frame structure?

    Sorry I was thinking of the last practise version I did. Each version has different values.

    What is the tension required for the crosspiece in an A-frame structure?

    ∑Homework Statement You are designing the crosspiece for the A-frame structure in the figure below. Beams AB and AC are 5.00 m long and have a mass of 375.0 kg each. How much tension must the crosspiece EF withstand? Assume that the mass of the crosspiece and the friction at points B and C are...
