A horizontal beam of weight "W" is supported by the cable and a hinge.
The force that gets exerted on the beam with the hinge has a mostly vertical component.
The pull "P' is quite sufficient in keeping the 14-N block along with the weightless pulleys within the equilibriumTherefore the magnitude of T or Tension is option (C) 16N.
