  Can I also smoke two joints before I smoke two joints, and then smoke two more?

    At that point you will have smoked 4% of 100 joints. Hey, math is easy.

  Did engineers come up with that last one though?

  Yes, in elevators usually one cable could hold far more than the full weight, than they add 6 more for the safety.

  For rail speed limits this is the exact way they calculate it. For road speed limits they consider break distance, which grows by the square of your speed, so if you go 120 on 60 road, you will need 4 times the distance to stop. I wrote 1.5 as a safety factor, not 4, With a 1.5 safety factor you can go by 75 though, but I would use a 1.1 safety there, as in my country the speed cameras are set up that way, you can go +10% of the official speed limit, they only send a cheque if you went even quicker than that.

    That’s because elevators use counter weights usually equal to the weight of the car and half the occupancy load so that it takes less energy to lift it and if it falls for any reason it won’t hit the bottom as long as the counter weights are still attached. The occupancy load is determined by the counter weighting system not the cable load capacity.

      Yeah, as I understand it, the elevator will refuse to move instead of collapse, and hopefully you’re not between floors when it happens because it was close and someone shifted their weight or bounced slightly or they might write a sitcom episode about what happens next (and the reality will be far more boring).
