The calculator below can be used to calculate the support forces - R 1 and R 2 - for beams with up to 6 asymmetrically loads. For a beam in balance loaded with weights (or other load forces) the reactions forces - R - at the supports equals the load forces - F. I'd like to know how much weight a 4X6, 4X8, and 4X10 wood beam can carry over a 15 foot span. The weight would be evenly distributed.

- The type of load in question will also determine how much weight a 2x6 can hold on edge. For example, a 2x4 lumber may hold a 4-cylinder engine comfortably but may not hold a bigger one. On the other end, a 2x6 can support a V8 engine of between 600 – 700 lbs.
- It seems you need to use 152 x 102 x 4.763 mm rectangular tubes for your two horizontal beams. These would have the same weight as the square tube beams in post 15, but would instead give the following results for the post 15 load case using daf = 1.75, except including self weight.

How Much Weight Can A 4x6 Support
The span of a beam is dependent on a few variables. The species of lumber, size of lumber and the load it carries. Fewer posts on upper level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans. Beam span maximums are based on a maximum anticipated live load. Building codes for residential decks only require 40 psf.
The longer the joist, the more area of deck the joist supports, and thus the beam supports. For pressure-preservative-treated southern pine no. 2 grade, there is a method that can be used for estimating beam spans for a preliminary design. When supporting joists that span 12 feet with no overhang beyond the beam, a double ply beam can span in feet a value equal to its depth in inches. A double 2x12 beam can span 12 feet; a (2) 2x10 can span 10 feet and so on.

The numbers in gray indicate the distance between the support posts. Numbers in blue are joist spans ( beam to beam or house to beam)

Douglas Fir-Larch, Hem-Fir, Spruce-Pine-Fir, Redwood, Cedars, Ponderosa Pine, Blitzkrieg 2 anthology for macbook pro. You don't get to choose your unit type though: for instance, your heavy german tank will be determined by the mission script; you can't eventually, let's say, unlock a Tiger 2 after a mission to use it for the next one instead of a Tiger 1, which you can do in BK1. Blitzkrieg 2; each mission is specifically scripted (in BK1, missions are randomly generated and quite repetitive, except maybe the final battle of each scenario), you also get better graphics and camera control, plus you decide which units will gain veterancy by giving them commanders, you also have more defensive or offensive options for your units as they level up.
