Problem

A uniform horizontal beam

4\,\text{m}

long and weighing

400\,\text{N}

is hinged to a wall at one end. The beam is supported by a light cable attached to its free end and making an angle of

60^{\circ}

above the beam. Assuming equilibrium, determine the tension in the cable and the magnitude of the resultant force exerted by the hinge on the beam. a)

T = 400\,\text{N},\; R = 207\,\text{N}

T = 230\,\text{N},\; R = 231\,\text{N}

T = 231\,\text{N},\; R = 346\,\text{N}

T = 462\,\text{N},\; R = 231\,\text{N}
