As a engineer, it's your JOB to research the problem. I really don't understand why you can't use the assets in front of you!!!!?? The internet, Google, YouTube, etc. I my day, you had to use the library, books, magazines, microfilm, etc. I won't help you because the art of engineering is about creative thinking. Not just the math and science. And what's frustrating is that there are engineers out there that can't "think andchew gum" or build anything from IKEA in the field.
