Brass Chandioler meets a 25' drop!

[aametalmaster]

A nice little project that came in today. A giant 100 lb 4' tall brass chandioler that cost 5 grand in 1984 fell 25' and smashed. It should be a pretty easy fix it just looks bad all mangled. I need to make a new rod that goes up thru the middle for a frame and weld brass tabs on the arms and redrill the holes to mount. The pcs on the left with the blue tape are fine. Hopefully i don't have to mess with the wiring too much...Bob

ouch! good thing it didnt hit anyone... did it "just fall" or was there something to entice it to come loose?

I was first told it just fell. But when i picked it up i was told they use a hook to pull it over to the 2nd floor to change the bulbs so it may have been pulled...Bob

hehehe... sniker sniker. Well enjoy the rebuild.. if you have any wiring trubs let me know, I'll do what i can to help you out.

With the kind of work I've seen you do, it will look much better than new in no time. Dave

Kind of reminds of on those high school physics problems:

"A giant 100 lb 4' tall brass chandioler that cost 5 grand in 1984 fell 25' and smashed. What was the speed of the chandelier at impact?"

Ouch! My head hurts...

Simple to solve for time.

s= Vo2 (v naught squared) + 1/2 at2 (at squared)

Where s= distance
Vo2 = initial velocity squared
a= acceleration, 9.8 feet per second
t2= time squared

25 feet = 0 + 1/2 x (9.8 x 9.8) t2
25 = 1/2 x 96.04 t2
25= 48.02t2
.52061641=t2
.721537532=t

It takes .7 second for the chandelier to fall 25 feet. I don't know how to figure out what the velocity was at impact.

[SignWave]

25 ft/sec. should have been the velocity @ impact. In the first second, that chandelier would have accelerated to =32 ft / second, so 25ft in one second should = 17mph...? I think this is right. It failed Physics... was too busy chasing the girls getting 'A's in the subject...

So with that all said and done, how much did it weigh at the time of impact? hehehehe..

I'm not sure about everybody's math, but assuming crawler's calculations of time are correct -- if it fell 25ft in 0.7 secs, then wouldn't that mean it would have fallen 36ft in 1 sec? (25ft/0.7sec = x/1.0sec; 35.71ft/sec=x)

Now I'm gonna be having slide rule nightmares again

Well, keep the slide rule handy cause Im wondering how much damage it can do on a human scalp at 25ft/.7sec vs 36ft in 1sec or whatever speed it was going
