Steel Floor Safe
Is it safe to weld RSJ "T" and "X" joints ?
My builder has fitted a 5 metre 8" x 8" RSJ to reduce the bounce in an upstairs floor. He has then cut out sections from the top and bottom on both sides of the vertical to accommodate 8 x 8 RSJ's welded at right angles, forming a "X". I am concerned about the safety of this method of joining RSJ's particularly as the welds were made in situ and there appears to be no fusion at many point with the top (closest to floor above) not welded at all. Further, is it o.k. for the other end one of the "X" steels to be butted into an in-use chimney brest rather than the external wall and the other other "X" steel (approx 1 metre long) to have no support at the other end..

The welds look okay, but the lack of support of the meter long element is worrisome, as well as it being butted into the chimney brest. Overall, it looks a little like an amateur job, slapped together where it looks like maybe useful but without professional quality analysis. You should ask to see the stress and load calculations he based his work on.

If the train's speed is 12.0 m/s, what is shortest distance in which it can stop without the safe sliding?
A train car with a steel floor is carrying a steel safe. The coefficient of static friction for steel on steel is mu static friction=.800. If the train's speed is 12.0 m/s, what is shortest distance in which it can stop without the safe sliding?
The maximum force that can be exerted to stop sliding is 0.8 x M x g where M is the mass of the safe.
Using F=ma we find that the maximum acceleration is thus -0.8g
Using v^2= u^2 + 2as where v = 0; u = 12m/sec you can determine the distance.
