A 11.0 m uniform beam is hinged to a vertical wall and heldhorizontally by a 5.00 m cable attached to the wall 4.00 m abovethe hinge, as shown in the figure below . The metal of this cablehas a test strength of 1.20 kN, which means that it will break ifthe tension in it exceeds that amount.
Find the horizontal component of the force the hinge exerts on thebeam.
Find the vertical component of the force the hinge exerts on thebeam.
