Structural analysis to estimate the approximate safe load bearing capacity of his attic floor sure sounds fun on the other hand. We build 'em pretty big and feed 'em pretty well up here. Which is fairly well accounted for in older houses. So he's still got a margin to play with I'd imagine. At some point I'd start being wary about adding two piano mover sized guys carrying twice their weight again. Now I'm imagining working out the locations they can safely sit without putting too much load on the floor and underlying structures. Getting them into position one will of course have to follow carefully planned paths, possibly coordinating their movements to avoid temporarily exceeding any limits. Kind of like those old Sokoban games. Link to comment

Seems these days houses are made of pressed pine laminates and hardwoods a rarity; in our country anyway. Where I come from, the structural elements are mostly pine or spruce with no treatment whatsoever. Link to comment

Let's assume the average January temperature in Minnesota is 24 degrees F, but this year it was 32 degrees F. Someone has taken the values, converted them to centigrade, and reported the difference in centigrade. 24F = -4.4 C and 32F = 0C. The difference is 4.4 degrees C, which you've now converted to 40 degrees F. But the temperature wasn't 40 degrees F warmer than normal, because your average temperature in January wasn't 64F. Time to abandon that Fahrenheit stuff. Fahrenheit was the scientist. The temperature scale is Fahrenheit's monster. The Computer Audiophile and lucretius 2 Link to comment
