The Somerset & Mineral Point Railroad connected Somerset to what was then the Pittsburgh & Connellsville Railroad as it passed through Rockwood (then called Mineral Point) [5] in the early 1870s. The Johnstown & Somerset Railroad followed the Stonycreek valley north-by-northeast from Somerset through Stoystown to Johnstown around 1880.
In effect, the formula reduces the legal weight limit for shorter trucks with fewer axles (see table below). For example, a 25-foot (7.6 m) three-axle dump truck would have a gross weight limit of 54,500 pounds (24,700 kg), instead of 80,000 pounds (36,000 kg), which is the standard weight limit for 63-foot (19.2 m) five-axle tractor-trailer.

A loading gauge is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. Their purpose is to ensure that rail vehicles can pass safely through tunnels and under bridges, and keep clear of platforms, trackside buildings and structures. [ 1 ]
A forming limit diagram, also known as a forming limit curve, is used in sheet metal forming for predicting forming behavior of sheet metal. [1] [2] The diagram attempts to provide a graphical description of material failure tests, such as a punched dome test. In order to determine whether a given region has failed, a mechanical test is performed.
No. 18 with standard gauge Southern Pacific locomotive No. 3203 at Owenyo, California, in 1953. No. 18 was originally built in 1911 for the Nevada–California–Oregon Railway (NCO) as No. 12 until it was sold to Southern Pacific (SP) in 1926. [1]
HMS Rockwood was a Type III, Hunt class Escort destroyer of the Royal Navy, built by Vickers-Armstrongs in Barrow-in-Furness and served during the Second World War. She was damaged in action in November 1943 by a glide bomb , not fully repaired, took no further part in the war and was broken up for scrap in 1946.
As stalling is due to wing loading and maximum lift coefficient at a given altitude and speed, this limits the turning radius due to maximum load factor. At Mach 0.85 and 0.7 lift coefficient, a wing loading of 50 lb/sq ft (240 kg/m 2 ) can reach a structural limit of 7.33 g up to 15,000 feet (4,600 m) and then decreases to 2.3 g at 40,000 feet ...
Limits and Fits are standardized by the International Organization for Standardization (ISO) [2] and the American National Standards Institute (ANSI) [3]. Tables are used to quickly calculate required tolerances for bolt holes, shafts, mating parts, and many similar scenarios.
