Paraphrase! Conclusion To sum up, the design project problem wants the student to choose two different material that has different features from each other. In the end of the book, there is a variety of materials that student can choose of. After choosing the two different materials, students can use some of statics method to determine the forces on the machine to figure the required applied force out. Solving this applied force can lead to start working on the failure of buckling, yielding from the bending by using some assumed dimensions, and the applied force. As a result of solving for each material the recommended material is 1144 steel design 1 with 15 in assumption for the dimension. According to the strength of material and the low cost price. The two materials do the same work, so the cheaper will be the optimal design for the student. ————————————————————————- Praphrase it?
