Question

You open a restaurant and hope to entice customers by hanging out a sign (see the figure (Figure 1) ). The uniform horizontal beam supporting the sign is 1.60mlong, has a mass of 16.0kg , and is hinged to the wall. The sign itself is uniform with a mass of 26.0kg and over-all length of 1.20m . The two wires supporting the sign are each 34.0cm long, are 95.0cm apart, and are equally spaced from the middle of the sign. The cable supporting the beam is 2.10m long.

a)What minimum tension must your cable be able to support without having your sign come crashing down?

b)What minimum vertical force must the hinge be able to support without pulling out of the wall?

Answer 1
