What methods do the author use for his research and what method seems the most suitable?
Since all real objects are deformable when subjected to external or internal forces and moments, methods must be developed to analyze these forces and resulting deformations on the basis of the knowledge of material properties, solid mechanics.
Newtonian mechanics is the study of the motion of objects and bodies both solid and fluid. That portion of mechanics applicable to ship design considers solid bodies and fluids as continuous media.
Engineering students generally take separate courses covering various aspects of mechanics. They include:
1. Statics. The study of forces and moments on rigid, unaccelerated objects.
2. Dynamics. The study of the effects of forces and moments on the kinematics of rigid body motion.
3. Material science. The study of the properties of materials.
4. Solid mechanics or strength of materials. The study of the external and internal forces associated with the deformation of solid structures.

What are labs for?
A modem research laboratory is an important part of any scientific centre. Their researchers make their experiments and collect necessary data. New research often requires sophisticated experimental installations (internal combustion engines, power turbines) and up-to-date experimental facilities for accumulation data for the advancement of science (metres, registers, oscilloscopes, etc.). As a rule, a researcher plans his experiments to test his hypothesis. At present research in all fields depends on computer handling very large amount of data obtained from various experiments. A lab chief tries to equip a lab with reliable modern devices, organizes research groups, re-equips a lab with up-to-date machines and devices, staffs them with more research workers and engineers, improves the working conditions of the staff, gets funds, improves research activities.
Lab assistants and technicians keep lab equipment in good order, repair metres, check and adjust devices, clean instruments and apparatuses, adjust them, assemble new devices. If you want reliable information on the subject, if you want to verify your results, if you want to make the production more reliable, you can not go without doing research at a laboratory. You learn the methods for your experiment, make all the necessary preparations, make all measurements, process the results. If the method (approach) is suitable, if the experiment is well-designed, the data are in fall conformity with the theory.
