100%

An axial centric force of magnitude P = 400 kN is applied to the composite block shown by means of a rigid end plate. Knowing that h = 10 mm, determine the normal stress in (a) the brass core, (b) the aluminum plates.

Use units [N,mm]

Enter the answer to one decimal place. Do not round the invoices in the intermediate stages, but only the final answer!

Expert Solution
Step 1: Introduction

To obtain the correct result of these types of question certain compatibility equations are used. In this case the compatibility equation is:

The change in length of the aluminum plate= change in length in the brass bar

Thus, εA=εB

where, εA denotes the change in length of the aluminum plates

            εB denotes the change in length of the brass bar.
