LARGEST & HEAVY LOAD * Canada - Have you ever seen anything this large on the road? It’s crazy big.
* Alberta - How could trucks move this 1,000-ton load?
(Video: "946,000kg load headin towards Fort McMurray Alberta!!", by 181josh - Oct 12, 2015: Had to stop and video this massive load heading to Fort McMurray Alberta weighing in at 946,000kgs!!! )
-- What is it? I’m not completely certain—but the Internet says it’s some type of pressurized vessel to contain high pressure liquid (I would guess). Even though I’m just a mere physics professor and not a construction or road engineer I think this video is a great place to start talking about some of the cool things you can see in the video... Look at vessel compared to the size of the trailer. The trailer is way longer. Why? The answer is pressure. Pressure in the tires to be exact. The YouTube video says that the payload has a mass of 946,000 kg which would have a weight of 9.27 million Newtons. If you ignore the mass of the trailer, the ground has to push UP with this same force. That’s not so bad—buildings can have weights larger than that. However, there is one big difference between a building and a trailer: the area of contact. With a smaller area you can get a much larger pressure on the road surface... There is no way one truck could push that hard because there wouldn’t be enough frictional force between the tires and the road (oh and the engine probably doesn’t have enough torque). No, the only way to get this giant trailer to its destination is with 7 trucks...
