The Development of Heavy Equipment

– Imagine a world where the only earthmoving is what can shovel, and everything was pulled by draft animals. Up until 1850, when the steam traction was popularized, man power, draft animals, and a few simple machines was how earth was moved. Without the ability to change the contour of the land, structures had to be built in areas where the land had the proper contour. The need to move more earth more efficiently and change the lay of the land would grow as time went on. The power of steam has long been know….  

Evolution of Intermodal Transportation

– … This competition between truck transportation and rail transportation for long-haul freight hindered the growth of intermodal transportation since any cooperation would mean losing clients and jobs to each other (Lowe, 2005). This competition became spread between all modes of transportation, where each mode seeks to exploit its own advantages over the others and they viewed each other with suspicion (Rodrigue & Comtois et al., 2013). The government’s transportation policies also hindered any efforts for a integrated intermodal system…. ;

Pros and Cons of Funding the Construction of the Express Rail Link in Hong Kong

– In January of 2010, the Legislative Council have eventually approved the funding for the construction of Guandzhou-Shenzhen-Hong Kong Express Rail Link (XRL), which costs $66.9 billion. This astronomical cost raised a lot of discussions that whether the railway worthed it or not. The whole alignment of the XRL railway is about 140 kilometres with its intermediate stations in Humen, Longhua and Futian. Some have argued that the new railway could contribute to Hong Kong’s short-term and long-term development….  

Physics of Rail Guns

– The concept of a rail gun is simple: two parallel bars connected to a power source produce an electric field. This electric field can be used to propel a projectile along the bars. If enough amperage is provided, the projectile can achieve velocities of up to 4 km/s. The U.S. Army has been interested in the potential of electromagnetic guns for quite some time. In 1988 the University of Texas Center for Electromagnetics began work on a 9 MJ range gun, which would be designed to launch 2-4 kg projectiles at velocities of up to 4 km/s….  

The Evolution of the Telephone and Operator

– The Evolution of the Telephone and Operator A few nights ago I was sitting at the dining room table reviewing my research, when my roommate, Lucy, walked in and inquired as to my progress. We started talking a bit about telephones and telephone operators and she related a story about the telephone in her hometown. Lucy is from a small town in Ireland. She clearly remembers when, at the age of four (about twenty eight years ago), her family installed their first telephone. To make a call her family would turn the crank on their telephone which would then alert Mrs….
