Depends on the loads and the properties of the beam. Consult a structural engineer.
That depends on what it carries. All joist/beam manufacturers have span tables that will help you determine this.
It depends on the type of beam, the material, whether it is a bridge span or cantilever, the allowable deflection and safety margin needed. We need a lot more data on the application.
Use a steel beam.. That would be code.. steel w10x15 (50ksi) I beam.
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.
20 to 100 or more years, depending on harshness of environment b
How far can 1 by 6 span without support
W8 x 24
That depends on what it carries. All joist/beam manufacturers have span tables that will help you determine this.
It depends on the roof load and the actual clear span. Off hand, I would guess htat you haven't given this much thought. A rule of thumb for a steel truss is one inch per foot of span or in your case 40 inches. If you want to use a steel I-beam, you can get that from a good municipal library from the steel beam institute, but you are going to need a crane to place it. Dieter in Cincinnati
never remove a support without consulting a building contractor. it's there for a reason. when removing a support, you would have to replace or add plies to the existing beam in place, which is a complicated procedure.
You can reinforce steel by either decreasing the span length or increasing the stiffness of the steel. Reinforcing steel improves safety and design effectiveness and decreases deflection.
The span of the space frame structure refers to the distance between the load-bearing structures at both ends of the beam and the arch in the building, and the distance between the centers of the two fulcrums. Then the combination direction of the main beam formed by the combination of the steel bar and the ball node (or plate node) is the span direction. Then in the plane projection drawing of the space frame, among the width and length of the conventional rectangular space frame, the shorter side length is the span; the diameter of the circular or spherical space frame is the span. The exact distance is based on the distance from the center of the support ball. The span of the arch shell is the chord length of the circular arch, and the special-shaped space frame takes the most unfavorable direction of the force as the span direction (because the definition of the span is based on the beam), and so on. For example, the same quadrilateral, 6X30 rectangle, if it is 3 meters support spacing around the support, then the span is 6 meters; but if the distance between the supports is 3 meters, there is no support in a 30-meter direction, and only three sides are supported, then the span is 30 meters.

What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts

Tensile Strength -In architecture, the ability of a material to span horizontal distances with a minimum of support from underneath.
