Seeker Posted September 8 Share Posted September 8 Here's a cool vid about construction of the CN Tower. The music will drive you bonkers but there is some interesting shots of the final topping and the Toronto skyline at the end. Link to comment Share on other sites More sharing options...
Kip Powick Posted September 9 Share Posted September 9 The music was "OUCH ". Interesting and I guess technology for video photography wasn't that good back then. Loved how all the workers were so safety conscience with the (tie-offs) he said sarcastically. 63 Millon back then and almost 4 years. Do it today and it would 10 years due to safety constraints, union strikes etc. and cost “estimate” about 320 million. Surprisingly only one worker died during the build. A piece of plywood fell, hit a worker on the ground in the neck and killed him. Link to comment Share on other sites More sharing options...

Don't know if you did the math on that or are some kind of math savant! While watching the clip towards the end with the guy driving pins in the top section with a 5lb sledgehammer all I could wonder was what's the terminal velocity of a sledgehammer dropped from 1800' AGL and how big the hole in the sidewalk would be?

The terminal velocity would be almost exactly as a muzzle velocity of a 9mm bullet leaving a Glock 19.......1154ft/sec The area of impact would depend on where on the sidewalk the hammer hit. Assuming the normal concrete sidewalk which is poured with expansion slots........centre...would probably star crack the entire section, .....outside edge - 1/2 star crack......open joint between two sections ..disjointed star crack in two sections.. The depth would depend on the sub strat under the concrete pour and the depth of the concrete Have a nice week... Link to comment Share on other sites More sharing options...

Further calculations show the kinetic energy is almost exactly the same as a 2000 kg vehicle traveling at 40 kph and, although travelling at the same speed as a bullet, the amount of energy is 356 times greater due to the higher mass. To convert to something easily understood - the hammer would hit the ground with the same energy as is contained in 30 Big Macs or what an average horse would eat in two days or what a 35 lb dog would eat in a month.
