A cantilever composite beam is formed by bonding together brass bar (Eß = 100 GPa) and aluminium (EA = 70 GPa) with cross section and loading at free end as shown in Figure Q1. Parameter x, y, and z are given by: x = last digit of your matrix number y = fifth digit of your matrix number z = fourth digit of your matrix number For example, a student with the matrix number CD200123 will have the values of 5x = 53, 4y = 42 and 2.z = 2.1. QI (a) Determine the centroid and the moment of inertia of the composite section. (b) Calculate the maximum tensile and compressive stresses in the brass and aluminium.

A cantilever composite beam is formed by bonding together brass bar (EB = 100 GPa) and
aluminium (EA = 70 GPa) with cross section and loading at free end as shown in Figure Q1.
Parameter x, y, and z are given by:
x = last digit of your matrix number
y = fifth digit of your matrix number
z = fourth digit of your matrix number
For example, a student with the matrix number CD200123 will have the values of 5x = 53, 4y
= 42 and 2.z = 2.1.
(a)
Determine the centroid and the moment of inertia of the composite section.
(b)
Calculate the maximum tensile and compressive stresses in the brass and aluminium.
(c)
Calculate the radius of curvature of the beam.
