You open a restaurant and hope to entice customers by hanging out asign (see the figure ). The uniform horizontal beam supporting thesign is 1.70 long, has a mass of 16.0 , and is hinged to the wall.The sign itself is uniform with a mass of 35.0 and over-all lengthof 1.20 . The two wires supporting the sign are each 40.0 long, are80.0 apart, and are equally spaced from the middle of the sign. Thecable supporting the beam is 2.20 long.

a) What minimum tension must your cable be able to support withouthaving your sign come crashing down?
b) What minimum vertical force must the hinge be able to supportwithout pulling out of the wall?
To be honest. I don't really understand where to begin...
