[2] In the United States, common sizes for steel shelf angles include L 3" x 3" x 1/4" and L 4" x 4" x 1/4".In the UK and Europe shelf angles / masonry support are predominantly manufactured in stainless steel to prevent corrosion and failure. These are bespoke to the building's frame and engineered to take the loads required.
Slotted angle (also sometimes referred to as slotted angle iron) is a system of reusable metal strips used to construct shelving, frames, work benches, equipment stands and other structures. The name derives, first, from the use of elongated slots punched into the metal at uniform intervals to enable assembly of structures fixed with nuts and ...
After leaving the station, the Mean Streak train passed through the storage tracks and made a 180-degree turn to the right, before ascending the 161-foot-tall (49 m) lift hill. After cresting the top of the hill, the train dropped 155 feet (47 m) at a 52-degree-angle, reaching a top speed of 65 miles per hour (105 km/h).
As with most steels, A36 has a density of 0.28 pounds mass per cubic inch (7.8 grams per cubic centimeter). Young's modulus for A36 steel is 29,000 kilopounds per square inch (200 gigapascals). [6] A36 steel has a Poisson's ratio of 0.26 and a shear modulus of 11,500 ksi (79.3 GPa). [7]
Once the train is dispatched, the train ascends the 45-degree lift hill at 13.2 miles per hour (21.2 km/h) to a maximum height of 305 feet (93 m). Once the train crests the top of the lift, the train descends down the 300-foot (91 m), 85-degree drop, reaching speeds up to 90 mph (145 km/h).

ASTM A992 steel is a structural steel alloy often used in the US for steel wide-flange and I beams. Like other carbon steels, the density of ASTM A992 steel is approximately 7850 kg/m 3 (0.2836 lb/in 3). ASTM A992 steel has the following minimum mechanical properties, according to ASTM specification A992/A992M.
