Brass Chandioler meets a 25' drop!

I dont believe its possble for that to occur in the first second of freefall. it would have to be less than 32 ft/sec.

This is great and reminds me of a great hunting camp story! My math is good and I took both Cal and Phys in college and for some reason unknown to man accelerated very well and sucked miserably every where else with the exception of lunch. In any event and not related to the aforementioned, I a-long with long time hunting friends were debating ballistics in front of a cozy fire in the North Eastern woods of Oregon on our annual deer hunt. The discussion was very involved and even heated at times as we challenged each others wits. Dead front, mid and down range energy along with flat trajectory and muzzle velocity were all taking a serious beating along with the camp growler (the hole in the dirt behind the big tree) as we just finished a hardy helping of wilderness chili stew. While I argued that my 270 was the gun of choice for our location (being flat and often requiring a 150 to 250 yard shot) others argued that a 30-06 or even the age proven 30-30 was a better choice in the event a tree were to jump in the way. And of course you always have the Tim Allan guy there with the 300 Win Mag in case some grizz got of course and darted down from Canada or Alaska. Somewhere into the second hour or so of this wonderful debate, I noticed Randy (one of the guys son) wondering just outside of the campfire lightly tapping two sticks together. At the time Randy was about 11 years old and a gifted shot with his 30-30. I wasn't sure just exactly what he was doing but surmised he was snipe hunting or perhaps warding off any sasquaces that may be lurking around the area. I decided to put my end of the debate on hold as I figured these guys had a enough steam to keep the momentum going in my absence and pay a visit to Randy who at that time was attempting a double tri-fold smore. I was curious about the stick banging as he was very methodical in his delivery. Not to insult him I first asked him if he would share his newly formed smore with me. He agreed and as we both looked at his new creation he not I, realized that perhaps a new debate could be formed on the best way to consume this monster smore. Since we were in the neighborhood of the previous debate I posed the question. "Randy, I noticed that you were banging two sticks together back there by the fire. What was that all about"? "Oh he says" with an uplifting smile, "I was just wondering if the deer on the other end gave a hamster's As~ about your math"? In short we all tend to pass the obvious to strike a debate with our fellow man of the cause or maybe better understood in this case as the delivery. The deer really doesn't care about how he was killed, all he knows or knew was that he was or is in very deep doo doo and could care less about our debate as we enjoy him with our garden salad and baked potato's.

All the calculations, speculations and inquires regarding this lamp brought me back to that night and if I can just add on last thing. In the unfortunate event someone had been under that lamp when it fell, they could give a Hamster's as! about the math.

Just fun guy's

I had to correct my errors. My original problem, I used 9.8 for acceleration. 9.8 meters/sec is correct, but since we're using feet, this needed to change to 32 ft/sec. Also, had to correct the formula. We don't use Vo^2 (v naught squared). I guess my memory is not so good from high school physics in 1982...

Here is a good reference I found on the internet.

**** Below is the correct version ****

<<<Use this formula to determine how long it will take an object to fall to the ground.>>

s= Vo (v naught) + 1/2 at^2 (at squared)

Where
s= distance
Vo = initial velocity
a= acceleration, 32 feet per second
t2= time squared

25 feet = 0 + 1/2(32) t2
25 = 1/2 x 32t2
25= 16t2
1.5625=t2
1.25=t

It takes 1.25 seconds for the chandelier to fall 25 feet.

======================================

<<To calculate terminal speed when it hit the floor:>>

where
v= velocity
Vo= initial velocity
a= acceleration (32 ft/sec)
t=time

v=Vo + at
v=0 + 32(1.25)
v=40

Velocity of chandelier hitting the floor is 40 feet/second.

hehehehe, I kneew that! I was just seeing if you knew!!

something didnt seem right about the distance to the floor, but hey, that sure was some tasty deer!!!

[jonnymag]

I'm just amazed that someone took the trouble to calculate it!

[storts]

If it was going 10,000 ft per second,it still has to be repaired!!!!!!,,I agree with Johnny Mag!!!!!!my 2 cents,Jack

My exact thoughts!

Who cares how fast it was going, and who cares how hard it hit. I'm just glad it fell so we can watch Bob do some mighty fine repairs on it. Dave

Well Bob,
Hows it going? are you making any headway? Is it..."falling into place" as it should ? Is it going as "fast" as it should? hehehehe..

I am told it is better to be a smart as$ rather than a dumbAs$...

Its going great. Got the big dent out of the big 12" brass ball, just need to weld a small crack and little dent and repolish. I used to help a guy polish those big old phonograph brass horns 500 at a time so i know how to polish and have the equipment. Cut some new tabs from brass plate to braze on to the arms but i need to make 2 fixtures to hold them right then make a new rod to hold everything straight because the old one is bent...Bob
