Question

Figure Q2 shows an arrangement used to transfer materials F to a construction site. The rod OB is fixed at datum O. One of the systems used have dimension and loads as given in Table Q2. During operation, Pulley A is rotated as shown to move the load upwards. The inclination angle of rod OB is θ = 45O.

 

Determine:

  1. Stress in Rope 1 (in MPa)                                                           
  2. Stress in Rope 2 (in MPa)                                                             
  3. Extension in Rope 2 (in mm)                                                            
  4. The minimum diameter of Rope 2 (in mm) if the stress is at yield
