This question makes no sense. A 90 lb load per sq. ft. refers to an area. To calculate the stresses on beams supporting an area you have to know the spacing between adjacent beams as well as the span. p.s. This qn when fixed belongs in mechanical engineering.
That question cannot be answered without knowing the load on the beam.
There is only one way to properly size an ac unit or a furnace. That is by performing a load calculation. This is a process that takes into account the construction features of the home. It is also based on weather data for the specific location of the home. For more information you can click on the load calculation page at http://www.hvac-for-beginners.com
depends on the train, size, weight, composition of the steel used for the tracks, wheels, weather, breaking system...
The basic idea of fault tolerance through redundancy is to size the system so that there is at least one more unit than the minimum required to carry the load. Thus, if a load is 10 amperes, a fault tolerant redundant system might have three (3) 5 ampere units in parallel;one more than is needed, hence: N+1 redundancy. The failure of any one power module leaves sufficient power available to support the whole load.

IPE is an acronym relating to medium size flange I-Beams manufactured according to the Euronorm 19-57 standard
A DLH will work.
What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts
That depends on many other factors. What is the beam material? Is the load a point load concentrated in one spot, or is it uniform across the total span? Specing beams is something that should be left up to a qualified person.

Wood beams can be joined in different ways. Traditional joinery uses mortise and tenon connections with wooden pegs drilled through to hold the beams together. Steel plate joinery uses metal plates and bolts. Simpson is a company that makes simple fasteners for wood connections. Steel connections can be made to order through a local steel fabricator. the important thing is to make sure that the joinery is strong enough to carry the loads that the beam carry. Often the help of a professional engineer is required to size the beam and connections whether wood or steel is used.
The amount of weight a steel I-beam can hold depends on its size, shape, and the material it's made of. Typically, steel I-beams are designed to support heavy loads such as building structures and bridges. Consult a structural engineer to determine the specific weight capacity of a steel I-beam for your project.
You should really consult an engineer or a framer. There are other factors to be considered.
Steel is stronger than concrete. By adding some reinforcement in the compression zone of a beam, it's bending strength can be increased without increasing the size of the beam. The steel increases the compression strength, while the concrete prevents the slender steel bars from buckling.
