That depends on what it is carrying. . .you definitely need to consult a structural engineer for this information, and having the original set of plans to show him will help. FYI. . .28 feet is a VERY long clear-span for any type of beam.
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.
The size of the beam needed to span 10 feet for roof support depends on various factors, including the type of material (wood, steel, etc.), the load it will carry, and local building codes. For a typical wooden beam, a common choice might be a 2x10 or 2x12, but calculations based on specific load requirements and spacing are essential. It's advisable to consult a structural engineer or local building codes to determine the exact specifications for safety and compliance.

The most accurate method to determine the appropriate beam size using an LVL beam size calculator is to input the specific dimensions and load requirements of the project into the calculator. This will provide a precise recommendation for the correct beam size needed for the job.

To span a distance of 20 feet, a lumber beam of at least 2x10 size is typically needed for adequate support.
The recommended size and material for a support beam to reinforce a load-bearing wall in a residential structure is typically a steel or engineered wood beam that is sized according to the specific load requirements of the wall. It is important to consult with a structural engineer to determine the exact specifications needed for the support beam.
The average weight of an H-beam can vary depending on its size and specific dimensions (height, width, thickness). In general, H-beams can range from a few pounds to several hundred pounds per foot in weight. It is best to refer to the manufacturer's specifications for the specific weight of an H-beam.
The normal size of a plinth beam is typically between 9 inches to 12 inches in thickness and 9 inches to 12 inches in depth, depending on the structural design requirements and load-bearing capacity needed for the building.
The amount of concrete needed per fence post typically ranges from 50 to 80 pounds, depending on the size and depth of the hole.

The formula for calculating the spot size of a laser beam is given by: Spot Size 2.44 (wavelength focal length) / beam diameter
It depends on the size of the system. On average about two to four pounds.
That can't be answered without seeing the details of your plans.
There are too many variables to consider for your application. You should consult a qualified engineer for this project.
