You want to hang a \(10-\mathrm{kg}\) sign that advertises your new business. To do this, you use a pivot to attach the base of a \(5.0-\mathrm{kg}\) beam to a wall (Figure P12.36). You then attach a cable to the beam and to the wall in such a way that the cable and beam are perpendicular to each orher. The beam is \(2.0 \mathrm{~m}\) long and makes an angle of \(37^{\circ}\) with the vertical. You hang the sign from the end of the beam to which the cable is attached.

(a) What must be the minimum tensile strength of the cable (the minimum amount of tension it can sustain) if it is not to snap?

(b) Determine the horizontal and vertical components of the force exerted by the pivot on the beam.
