Question
A steel rod is subjected to a gradually applied load (F) which gave a rise to a maximum
stress of 200 MPa. The rod is 250 mm long and one part of its length is square and the
remainder is cireular with a diameter of 25 mm. If the total strain energy in the rod and
modulus elasticity of the material is 1.3 J and 200 GPa, detemine the following:
4.3
The length of the square portion of the bar
The suddenly applied load that will induce the same amount of energy
4.4
4.5
The load that falls from a height of 8 mm induces 1,3 J in the bar.
