Triple? That sounds an awful lot like gluelam... Which requires engineer approval to meet code. The inspecting engineer will be able to tell you.
About 5metres(16') but would have to be stress graded timber.
Not sure why you need a beam that bears no load. You can go 22'. Beyond that it needs to be broken down to shorter lengths.
A typical sensitivity triple beam balance usually has a maximum weight capacity of 610 grams.
The Triple Beam Balance is a typical mechanical balance. It has a beam which is supported by a fulcrum. On one side is a pan on which the object is placed. On the other side, the beam is split into three parallel beams , each supporting one weight.
Depends on the area above the ceiling joists. Is it a live load (living space) or dead load (just the joists with maybe an attic above)? Also, the length of the ceiling joists from the last bearing point is a factor. How much weight is bearing on the beam is the critical issue.
A common alternative name for the triple beam balance is the triple beam scale.
in bio we call triple beam is a scale!
Depends on how much weight is above it!! but on 1 -2 story wood framed structures triple 2x12's glued and nailed will do the trick
A triple beam balance is a scale used to measuremass.
Triple Beam balances have 3 sliders.
The function of a triple beam balance is to find the mass and weight of an object
The triple beam balance is used to weigh an object's mass in grams.
