Please answer the following question 1-47 in the picture and make sure you draw a free body diagram also use positive sign convention for internal forces please, Thank for your help. Post pictures of your work instead of typing it.

Hint: this is a reverse engineering problem;
the force in the members can be computed by setting the equal stress condition.
