Question

A uniform beam, 1.5 metre long, is suspended in a horizontal position by two vertical support rods as shown in the figure below. Rod A has a diameter of 12 mm and manufactured from steel with Esteel = 210 GPa. Rod B has a diameter of 16 mm and is made from copper with Ecopper = 105 GPa. This simply supported beam is to carry a motor vehicle engine and gearbox weighing 5,5 kN.

  •  
  •  
  •  
  •  
    • Determine the distance ‘x’ from the left-hand support ‘A’ in order for the beam to remain in a horizontal position.
    • Calculate the stress in each rod due to the applied load.
    • Calculate the movement (extension) of the support wires under this 10 kN load.

Will the rods be able to withstand the applied load? Motivate your answer.
