A metal rod is 50 mm in diameter and 1.3 m long. The rod has a collar on one end and is suspended vertically. The height through which this load may fall if the instantaneous stress is limited to 90 MPa is 1.71870× 10−3 m. The value of Young modulus is 132.40 GPa. 2.1 Calculate an extension when a weight of 30 kN is suddenly lowered onto the collar. 2.2 Calculate the force required to cause the maximum stress.
