Hi there So we have a group design project in my mechanical systems 2 class and it basically goes as follows: design a mechanism to cut a half inch aluminum bar in half using a standard hacksaw blade and 4 AA batteries. You have to use a motor w/ input > 5000 rpm for the 'main' component we...

Hello all, This is my first post here. I will be transferring to University of North Carolina Charlotte (UNCC) in the fall with two associates degrees in Art and Science. I was accepted into the School of Mechanical Engineering. My original plan was to finish my undergrad, then go to grad...

The project I'm building involves a 12 V electric motor connected to a spindle lifting a 20kg weight. The radius of the spindle is 2cm, so the torque applied by the weight is 0,02m*20kg*9,8m/s^2, which gives me 3,92N*m. So, my 12 V motor needs to deliver 3,92N*m just to keep the weight steady...

So I was talking to one of my friends who is a huge programmer, and he said that you don't even need a computer science degree to work in software. He said that companies would rather teach a mechanical engineer how to program, than a computer science grad how to problem solve, and that out of...
