Question:

A crane boom is 10 m long and has a mass of 2000 kg. The crane is holding a load of 8000 kg. The crane boom makes an angle of 50{eq}^{\circ} {/eq} with the horizontal. Find the tension in the hoisting cable that makes an angle of 10{eq}^{\circ} {/eq} with the crane boom. The center of gravity of the crane is at its midpoint.

Force Equilibrium:

Force equilibrium is the state in which the force acting in all the directions will be balanced. If we take force acting in the positive x-direction as a positive force and in negative x-direction negative force, the net summation of the force in x-direction will be zero for force equilibrium.

Given data

  • The mass of the crane boom is: {eq}{m_1} = 2000\;{\rm{kg}} {/eq}
  • The load is: {eq}{m_2} = 8000\;{\rm{kg}} {/eq}
  • The length of the...
