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 circular 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: The applied load F The total extension of the bar The length of the square portion of the bar The suddenly applied load that will induce the same amount of energy The load that falls from a height of 8 mm induces 1,3 J in the bar.
