机械工程是最广泛的工程学科。德州理工大学机械工程系的毕业生完成了课程，为化学和物理的数学和物理科学奠定了坚实的基础，随后对五个主要机械工程领域进行了深入的教育：热科学，流体工程，机械和材料，动力学和控制以及机械设计。该系的毕业生将找到广泛的就业机会，包括航空航天，汽车，石油生产和精炼行业，电力，电子，半导体，制造和生产以及工业和政府实验室的研究职位。机械工程课程中学习到的解决问题的技术还应用于工程学以及法律，医学，工商管理和其他专业领域的继续教育追求或研究生学习。
Mechanical Engineering is the broadest of the engineering disciplines. Graduates from the Department of Mechanical Engineering at Texas Tech University complete a curriculum that provides a strong foundation in mathematics and the physical sciences of chemistry and physics followed by an in−depth education in five of the principal mechanical engineering areas: thermal science, fluids engineering, mechanics and materials, dynamics and controls, and mechanical design. Graduates from the department will find employment opportunities covering a wide spectrum, including the aerospace, automotive, petroleum production and refining industries, electrical power, electronics, semiconductors, manufacturing, and production, as well as research positions in industry and government laboratories. Problem-solving techniques learned in the mechanical engineering curriculum are also applied to continued educational pursuits or graduate study in engineering, as well as in areas such as law, medicine, business administration, and other professions.
