Two Short Math Problems

Two Short Math Problems

Do you ever read the ads that appear on ME Forum? I try to avoid them as much as possible, but an organization called BRILLIANT has put up some interesting math problems of late that have caught my eye. Two of them are the subject of today's post.

The first problem that I want to discuss is actually more recent than the other, but it gives us a good place to start. Following that, we'll go on to the second problem. Along the way, I want to talk about philosophy as well as simply how to solve tow specific problems. The main lessons to be learned here are in regard to how we use mathematics in the practice of Mechanical Engineering.

Excuse me for putting it up here.

my name is Hyun Soo Lee and I am a Korean high school student who visited once in January this year.I'm contacting you because I need your help.My dream is to be a robot engineer.I was told to write a report on the robot's assignment at school, can I explore robots?The exploration plan calls for the first to write about the subject of the exploration, the second to write about the purpose and hypothesis of the exploration, and the third to write about the research, theoretical background and necessity, experimental methods, and analysis results.Because if I want to explore, I have to make a hypothesis, because robots don't have a hypothesis.Now, what I thought about now is how to reduce the rate of injury to the robot as it falls. We've looked at the angles of the bridge, the minimum mass, the round structure instead of the angular structure, the material changes on the cladding, the way internal parts are fixed.But I think this is the first time I've ever had experience and I don't have much money, so I think there will be a lot of obstacles to this experiment. So I wonder if you could help me out. We would appreciate it if you could give us tips for making robots, or give us a topic about robotics that can give us a hypothesis.Is there a plan to explore the project a little higher than a high school student?Thank you for listening to me.
