A frame {eq}ABC {/eq} is supported in part by cable {eq}DBE {/eq} that passes through a frictionless ring at {eq}B {/eq}. Determine the magnitude and direction of resultant forces exerted by the cable at {eq}B {/eq} knowing that the tension in the cable is {eq}435 N {/eq}. Also, determine the components of the force exerted by the cable on the supports at {eq}D. {/eq} ( Round the resultant to the nearest number, and the directions to a single decimal place).

Resultant force

A single force that is able to replace all other forces that are acting on a body is termed as a resultant force. The resultant force is also exerted the same effect on the body as that of the system of forces.

Given data:

  • The tension in the cord of BD and BE is: {eq}T = 435\;{\rm{N}} {/eq}.
  • The position vector of B is: {eq}{\vec r_B} = \left( {480\hat i...
