Engineer in example sentence
So I'm an academic at MIT, and I'm a mechanical engineer, so I can do things like look at the type of terrain you want to travel on, and figure out how much resistance it should impose, look at the parts we have available and mix and match them to figure out what sort of gear trains we can use, and then look at the power and force you can get out of your upper body to analyze how fast you should be able to go in this chair as you put your arms up and down the levers.
