Some how I feel with all of the sightings earth has had from so many different countries; most recent mexico. Numerous ones. We are visited for some reason. All of us know something is going on that is abnormal outside of human awareness. I don't believe the government is run by them. The only way that would be true is our money is working on aircraft secretly invented. Maybe some day we will get the big surprise to travel to other galaxies. I really don't see why they haven't reshaped our rocket ship into saucer shape anyway. It would travel faster through the atmosphere from point A to point B. If you threw a ballpoint pen straight along with a quarter, which has the greatest balance and air velocity. I should have taken up engineering!

okay, so now I know that I am stressing my amp which spits out of two outputs a 4 ohms each into speakers at 8 ohms each. How would I go about correcting this? Would making a simple 2 to 1 speaker cable work? Plug both 4 ohm jacks into a single 8 ohm speaker?

I'm participating in a school underwater robotics team (rov). We have 3 motors controlling this rov, one on each side (left and right) and one for up and down in the center of the rov. All three motors are 2 directional motors. The way we would like to have the controlls setup is that we have 2 joysticks, one for each side motor. Then line the joysticks up side by side, have the left joystick control the left motor and the right joystick the control the right motor(up forward, down backwards), and then have one of the joysticks control the up and down motor (by moving the joystick left or right). Kind of like a bulldozer works. Is this possible and are there any suggestion on wiring this project. Thank you very much for your help.

you plug into an outlet that you would want on continuasly untill you pressed and held a button, but when you released the button, it turned back on?

In other words, what is something that you would plug into an outlet, that you would put a kill switch on. (but the kill switch only stops the electricity to the device while you hold down the kill switch button)

this is not a riddle or trivia question. I just need some ideas.

An engineering student has been given the assignment of designing a
hydraulic holding system for a hay baling system. The system has four
cylinders with 120mm diameter pistons with a stroke of 0.320m. the lines
connecting the system are 1 cm in id (inside diameter). There are 15.5
m of lines in the system. For proper design the reserve tank should
hold a minimum of 50% more than the amount of hydraulic fluid in the
system. If the diameter of the reserve tank is 30.48 cm, what is the
shortest height it should be?

I have researched this - but bridge design is very complicated and I can't come up with an estimate for this load in simple terms. I built a little roman arch model with a width of 4 in and span of 7.5 in. It holds 100lbs! I want to know what this 100lb. load might be in real-life. Is it a million pounds? My bridge is a single lane. I plan to build truss and beam bridges out of the same material to show how the design changes affect the max static load. My Dad says this is no way to design bridges but I'm having fun and this is not for a grade. Thank you.
