Concrete should be troweled to a smooth even surface and be aged for at least 90 days. Expansion joints should be properly filled. Neutralize the surface of the concrete. Use either 1 part Muriatic Acid and 9 parts water or 1 part vinegar and 5 parts water to make a good neutralizing agent.
Cedar Pointâs Top Thrill Dragster relies on the power density of hydraulics. August 29, 2014 By Mary Gannon Leave a Comment. As it embarked on yet another one of its record-breaking, thrill-seeking rides, Cedar Point quickly turned to hydraulics, for the power density and precision control it offers.
The steeper the bank, the greater the g-forces. This top-fuel dragster can accelerate from zero to 160 kilometres per hour (99 mph) in 0.86 seconds. This is a horizontal acceleration of 5.3 g. Combined with the vertical g-force in the stationary case the Pythagorean theorem yields a g force of 5.4 g.
