STEMExplore: Mechanical Engineer

The video features a staff mechanical engineer at Otis Elevator discussing the complexities behind elevator engineering, the global impact of elevators, and the varied daily tasks of an engineer. It emphasizes the importance of both theoretical knowledge and hands-on experience in engineering. The video also highlights innovations at Otis, particularly the Gen2 elevator, which is energy-efficient and can be powered by solar panels.

What is the primary role of elevators in urban development?

• To enhance building aesthetics

• To reduce traffic congestion

• To enable skyscrapers and urbanization

• To provide scenic views

What is a unique aspect of an engineer's job at Otis?

• Focusing solely on design

• Avoiding hands-on tasks

• Traveling to various countries
