This is a VERY BROAD subject, which OVERLAPS with lots of other types of engineering. However, the most common specializations of mechanical engineering include manufacturing, transportation systems, combustion, nanotechnology and robotics. Mechatronics engineeringmay also be of interest; this combines mechanical and electronic engineering with areas such as computer and control engineering
Nanotechnology has become of interest these days. My Gf is doing a research on effectiveness of nano materials in de-fluoridation of water from singida and shinyanga![emoji56][emoji56]
