Q9. A 24-tonne container is being lowered onto the deck of a cargo ship at a velocity of 0.1 m/s. It is evenly supported by three steel wires 75 mm in diameter and 25 m in length. The brake is suddenly applied. Calculate EACH of the following:

(a) The stress induced in each wire due to the sudden stop; (14)

(b) The resultant instantaneous wire extension. (2)

Note:

Modulus of Elasticity for steel = 200 GN/m².
