Is there a way to heat sheet metal uniformly so that it does not bow once it reaches a certain temp? (need to go to ~600F)

a brick slides down an inclined plank at a constant speed when the plank is inclined at an angle theta_0. if the angle is increased to theta_1, the block accelerates down the plank with acceleration a. the coefficient of the kinetic friction is the same in both cases.
given the two theta, calculate a.

We are trying to make the robot have more speed than torque as far as the wheels go. The total bot weight will be 12 lbs. The actual spinning weapon/armor will not exceed 8lbs. Would it be better if we have more speed than torque, to destroy the other robots? How much RPM do we need on the motor which will run on 12 V?

can we just all use 100 volts? that will help conserve electricity, right?

also, why just we all use DC instead of AC? this way, no one gets electricuted, no?

I have a circuit and I want to use 2 indicators. I thought that I would make one red amnd one green, but I don't want a combination because the person who uses it might be color blind and what about current?

I've been thinking about majoring in engineering next year in college and needed some opinions. What type of engineer are you? How long did you have to go to college for? Do you make a decent salary? And do you enjoy your job? Thanks!

the inputs of the system are inertial movements of an object (car). it outputs acceleration (from accelerometers) and attitude (yaw, pitch, roll - from gyroscopes). it is then processed and analyzed to compute for the movements the object had done. With an initial coordinate(starting location), the data may be used to find for the corresponding coordinates of the final position.(longitude, latitude, etc)... is my understanding correct?

I'm building a small coilgun (launches steel paper clips about a meter or two). Anyway, what I want to do is make it more powerful but with the same charging time (about 1 minute). I have four 1.5v batteries as the power supply and use the flash circuit of a used disposable camera to charge a 330v 120uF capacitor (originally belonging to the camera). I know that I should use larger capacitors to get more electricity into the coil. I tried using a 16v 10000uF capacitor which didn't work (I think this is because it takes too long too charge and didn't charge it long enough) and a 16v 4700uF capacitor that did sent a screw at a hammer about 3 cm away and bounced back (though I had to charge it for about 5 minutes, which is pretty long compared to the relatively short 1 minute for the camera flash capacitor).
So, any ideas on how to make the coilgun more powerful in less time (1 minute of charge should do)?

P.S.: Not sure if this is the category this question should be in.
