Use a steel beam.. That would be code.. steel w10x15 (50ksi) I beam.
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.
You must also take in consideration the width of the building. For instance a 12'x16' building you would use 2x6 rafters and a 2x8 beam with collar ties every 4'.
This is one of those questions that no one will will tackle because there are other factors that weigh into this type construction: Angle of lift, How will the new beam be supported, Is the foundation sufficent, indoors vs outdoor ect. Your safety is important, and you would be better served to discuss your needs with a engineer that can look at the whole picture. I built a overhead crane once with a 40' span once and I can tell you from experience you will not find a beam straight enough as delivered. It will have to be proffessionaly straightened. Mine was a 24 x 100# I-beam and it had a 18" bow that had to be corrected.
There are many established methods of solving deflection of beam. Some notable methods are as follows.Double integration methodArea-moment methodMethod of superpositionConjugate beam methodCastigliano's TheoremThe most widely used are the method of superposition and area-moment method. Links are provided in the related linksfor you to read the procedure for each method and many examples in simply supported beams.
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.
What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts
To calculate the total number of deck boards needed for a deck that is 5 feet wide and 4 feet long, you would first find the perimeter of the deck, which is 18 feet. Since each deck board is 4 feet long, you would divide the perimeter by the length of each board to get the total number of boards needed, which is 4.5 boards. Since you can't buy half a board, you would need to round up to 5 boards.
Most products like deck sealer will tell you on the can how many square feet it will cover.
i have a 1250 square foot deck and need to figure out how many linear feet of decking material I need. the boards are 6 X 10
You will need to bridge the spring place a beam supported on either side over the top of the spring and support of that instead
In general, boats with a beam over 8'6" will require a permit, but are still considered 'trailerable'. Around twenty five feet or so, boat trailers are no longer an option and the boat will need to be placed on a truck for transportation.

To calculate the square footage of a concrete swimming pool deck, measure the length and width of the deck in feet and multiply the two measurements together to obtain the total area in square feet. Keep in mind that if the deck is not a perfect rectangle, you may need to break it down into different sections and calculate the area of each section separately, then add them together to get the total square footage.
To build a 12x30 deck using 2x6 boards, you need to determine the total area of the deck and the coverage of each board. The deck area is 360 square feet (12 feet x 30 feet). A 2x6 board typically covers about 5.5 inches in width (actual size), so you can fit approximately 5.5 boards across the width of the deck (12 feet = 144 inches). With 30 feet length, you would need around 33 boards (30 feet / 1 foot per board) to cover the length, resulting in approximately 165 boards total (33 boards x 5). Therefore, you would need around 165 2x6x12 boards, but it's always wise to account for waste and cuts, so purchasing a few extra is recommended.
Oh, dude, math time! So, to cover a 28x16 deck, you'd need 448 square feet of decking. Each 5/4x6x8 board covers about 2.22 square feet, so you'd need roughly 202 deck boards. But hey, maybe grab a few extra in case you miscount or your neighbor's dog decides to snack on one!
About 160 feet - just about the distance you need if you slam on the brakes for a sudden stop!
To cover a 10x10 deck with 1x4x10 boards, you'll first calculate the area of the deck, which is 100 square feet. Each 1x4 board (which measures 3.5 inches wide and 10 feet long) covers approximately 2.92 square feet. Therefore, you'll need about 34 boards (100 ÷ 2.92 ≈ 34.25) to cover the entire deck, rounding up to account for cuts and waste.
