A composite shaft is comprised of a solid upper part made of aluminium with an elastic modulus of 80 GPa, diameter of 40 mm, and length of 100 mm, and a hollow lower part made of steel with an elastic modulus 200 GPa, outer diameter of 60 mm, inner diameter of 15 mm, and a length of 150 mm. The composite shaft is designed to absorb 80 joules of energy for deformation within its linear elastic limit upon application of an axial load onto a collar attached to its lower end. Determine the stress induced in and magnitude of the force acting on it for the cases of: (i) A gradually applied load. (ii) A suddenly applied load. (iii) A mass that is dropped onto the collar from a height of 150 mm.

Question
A composite shaft is comprised of a solid upper part made of aluminium with an elastic
modulus of 80 GPa, diameter of 40 mm, and length of 100 mm, and a hollow lower part made
of steel with an elastic modulus 200 GPa, outer diameter of 60 mm, inner diameter of 15 mm,
and a length of 150 mm. The composite shaft is designed to absorb 80 joules of energy for
deformation within its linear elastic limit upon application of an axial load onto a collar
attached to its lower end. Determine the stress induced in and magnitude of the force acting on
it for the cases of:
(i) A gradually applied load.
(ii) A suddenly applied load.
(iii) A mass that is dropped onto the collar from a height of 150 mm.
