Elements of Structures MIT 2.02

In this problem
The composite beam AB, of length L=2m, is free at A (x=0) and fixed at B (x=L) and is composed of a round cylindrical core of constant radius R0=1cm bonded inside a sleeve of thickness R0 (outer radius 2R0=2cm). The beam is loaded, as indicated, by a downward linearly varying distributed load per unit length of magnitude
The material moduli are:
For the core, EC=70GPa=E0
For the sleeve, ES=210GPa=3E0
Now i got
max STRESS in CORE=9 MPa
and max stress in sleeve= 73 MPa
Are this values correct ? Ples help me this are the last values to finish and I have only more chance and I will pass the course.
