The weight of the engine in kN is given in P2 and is suspended from a vertical chain at A. A second chain round the engine is attached at A, with a spreader bar between B and C. The angles at B and C are equal and given in P3. Determine the tension in the chain AC in kN to 1 DP and determine the compressive force acting in the spreader bar BC.
The tension in the chain AC in kN rounded to 1 DP is ANS: The compressive force acting in the spreader bar BC in kN rounded to 1 DP is ANS:
