What size spruce beam header would you need to span 12 feet while supporting the center of a truss roof?

What size you i beam can safely span 40 feet with 1000lb capacity in the middle?

To span 40 feet with a capacity of 1000 pounds in the middle, you would need to consider various factors, such as the material of the beam and the desired safety factor. Generally, a W18x55 or W21x55 steel I-beam could be suitable for this application. However, it is recommended to consult with a structural engineer for a precise assessment based on the specific loading conditions and design requirements.


How do you calculate deflection on a simply supported beam?

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.


How much weight can a 6x6 steel i-beam support?

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.

How do you calculate the square footage of a concrete swimming pool deck?

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.

How many linear feet of wood do i need of decking for a 12 foot by 12 foot deck?

It depends on how wide your lengths of wood are.


The deck is to be 16 feet long and 21 feet wide and the decking material was priced at 45.00 a square yard What would be the cost in dollars of the decking material?

1 square yard = 3 feet * 3 feet = 9 square feet. The deck is 16 feet * 21 feet = 336 square feet. Dividing by 9, the deck is 37.333 square yards so you will need at least 38 packs of decking. You will need more to allow for wastage - end pieces that are cut off but are too small to use elsewhere. 5 per cent wastage is good going; 40 packs allows you 7% wastage and will cost USD 45*40 = USD 1,800.
