COMMENT

1. Regarding the thesis content and implementation volume:
.................................................................................................................................................
..................
...

...
omplete this thesis as best as possible
with the knowledge they had learned and the guidance of Assoc. Prof. Dr. Do Thanh Trung,
Assoc. Prof. Dr. Pham Son Minh and Dr. Tran Minh The Uyen. Due to the limited time to
carry out the thesis and write the report, our thesis will inevitably have shortcomings. We
respectfully hope to receive your enthusiastic comments and guidance.
5.2.

Study direction and future development
During the process of studying and implementing the project, in addition to the results

achieved, the group did not test different types of plastic to compare the influence of different
types of plastic on torque..
Therefore, our group hopes that the following groups of students will continue to study
the remaining issues to make the thesis more complete.
