To succeed your mission, you should apply stress and deformation analysis to the steel arm by following the below steps:
1. Describe the problem without addressing any possible solutions – Problem definition.
2. Measure the arm size and draw the sketch of the Steel Arm ABCDEFG that shows all
needed dimensions.
3. Define the maximum force that the athlete can apply at both handles and show it on
the sketch of the Steel Arm.
4. Conduct research and gather information to determine the materials used in the arm.
5. Show the properties of the selected material in a table.
The Chair
The Arm
6. Describe further work that needs to be done to complete the study – Work plan.
7. Prepare a minutes of meeting (MOM) covering all the issues discussed in the meeting
including but not limited to the following points:
• Function of team leader and team members.
• The Gantt chart describing all the further work (Work Plan).
• Other project management issues for periodic team meetings.
You are asked to study and analyze your Writing Desk Chair with right or left side Arm that hold the wooden tablet shown in figure 1. Your objective is to apply stress and deformation analysis to evaluate the maximum stress, deformation and the factor of safety in the main metallic arm ABCDEFG (Figure 2), within the elastic domain, if a 50 kg weight is equally distributed on the wooden tablet.
