Use a steel beam.. That would be code.. steel w10x15 (50ksi) I beam.
Depends on the material the I-beam is made out of. Steel? Is it a wood I-joist? And I-beams come in different "flavors" as regards the geometry and cross section of the web. Variables in a question make for a variable answer.
There are a lot of considerations to be taken into account for sizing steel shapes, especially for a residential home. For instance, what are the load imposed upon the beam? How will the beam be supported? What environment will the beam sit in (i.e. high humidity, moisture, vibration)? A licensed professional engineer or architect in your state can better answer this question.

With a span of only 8" you can probably use a wood beam, but without a set of plans no one can accurately answer your question.
The weight of 5 rebar rods can vary depending on the diameter and length of the rebar. As a general estimate, a standard size #5 rebar (5/8-inch diameter) that is 20 feet long weighs around 15.41 pounds. Therefore, the weight of 5 such rebar rods would be approximately 77.05 pounds.
well a low beam can be from nothing to 1 foot high a medium beam is 2 and a half feet high and a standard high beam is 3 and a half feet high

That question cannot be answered without knowing the load on the beam.
A Balance beam is 16 feet long and 4.5 inches in width and height varies.
High beam headlights can illuminate anywhere from 30 meters to 150 meters ahead of the car. This is 98 feet to 492 feet away.
