Pittsburgh has a total area of 58.3 square miles (151 km 2 ), of which 55.6 square miles (144 km 2 ) is land and 2.8 square miles (7.3 km 2 ) (or 4.75%) is water. The 80th meridian west passes directly through the city's downtown.
The city is on the Allegheny Plateau , within the ecoregion of the Western Allegheny Plateau , The Downtown area (also known as the Golden Triangle) sits where the Allegheny River flowing from the northeast and Monongahela River from the southeast form the Ohio River . The actual convergence is at Point State Park and is referred to as "the Point." The city extends east to include the Oakland and Shadyside sections, which are home to the University of Pittsburgh , Carnegie Mellon University , Chatham University , Carnegie Museum and Library , and many other educational, medical, and cultural institutions. The southern, western and northern areas of the city are primarily residential.
Many Pittsburgh neighborhoods are steeply sloped with two-lane roads. More than a quarter of neighborhood names make reference to "hills," "heights," or similar features. [a]
The steps of Pittsburgh comprise some 712 sets of outdoor public stairways with 44,645 treads and 24,090 vertical feet. They include hundreds of paper streets composed entirely of stairs, and many other steep streets with stairs for sidewalks. Many provide vistas of the Pittsburgh area while attracting hikers and fitness walkers.
Bike and walking trails have been built to border many of the city's rivers and hollows, but steep hills and variable weather can make biking a challenge. The Great Allegheny Passage and Chesapeake and Ohio Canal Towpath connect the city directly to downtown Washington, D.C. (some 245 miles (394 km) away) with a continuous bike/running trail.

QuestionTrucks and cars have much in commonmechanicallyas well asancestrally.One link between them is the steam-powered fardier Nicolas-Joseph Cugnot, who built it in 1769. Unfortunately for him, steam trucks were notreallycommon until the mid 1800's. While looking at thispractically, it would be much harder to have a steam truck. This ismostlydue to the fact that the roads of the timewere builtfor horse and carriages. Steam truckswere leftto very short hauls, usually from a factory to the nearest railway station.In 1881, the first semi-trailer appeared, and it was in fact towed by a steam tractor manufactured by De Dion-Bouton.Steam-powered truckswere soldin France and in the United States,apparentlyuntil the eve of World War I. Also, at the beginning of World War II in the United Kingdom, theywere knownas 'steam wagons'.

QuestionTrailer stability can be defined as the tendency of a trailer to dissipate side-to-side motion. The initial motion may be caused by aerodynamic forces, such as from a cross wind or a passing vehicle. One common criterion for stability is the center of mass location with respect to the wheels, which can usually be detected by tongue weight. If the center of mass of the trailer is behind its wheels, therefore having a negative tongue weight, the trailer will likely be unstable. Another parameter which is less commonly a factor is the trailer moment of inertia. Even if the center of mass is forward of the wheels, a trailer with a long load, and thus large moment of inertia, may be unstable.

QuestionAs of January 1, 2000, the Federal Motor Carrier Safety Administration (FMCSA)was establishedas its own separate administration within the U.S. Department of Transportation. This came about under the "Motor Carrier Safety Improvement Act of 1999".The FMCSAis basedin Washington, D.C., employing more than 1,000 people throughout all 50 States, including in the District of Columbia.Their staff dedicates themselves to the improvement of safety among commercial motor vehicles (CMV) and to saving lives.

QuestionThe feature film "Joy Ride" premiered in 2001, portraying the story of two college-age brothers who by a CB radio while taking a road trip.Although the plot seems lighthearted, it takes a quick turn after one of the brothers attempts a prank on an unknown truck driver. They soon find out the dangerous intentions of this killer driver, who is set on getting his revenge. Seven years later in 2008 the sequel "Joy Ride 2: Dead Ahead" came out on DVD only.Similar toits predecessor, the plot involves another murdering truck driver, a.k.a "Rusty Nail". Heessentiallyplays psychological mind games with a young couple on a road trip.

QuestionHeavy trucks. A cement mixer is an example of Class 8 heavy trucks. Heavy trucks are the largest on-road trucks, Class 8. These include vocational applications such as heavy dump trucks, concrete pump trucks, and refuse hauling, as well as ubiquitous long-haul 6×4 and 4x2 tractor units. Road damage and wear increase very rapidly with the axle weight. The axle weight is the truck weight divided by the number of axles, but the actual axle weight depends on the position of the load over the axles. The number of steering axles and the suspension type also influence the amount of the road wear. In many countries with good roads, a six-axle truck may have a maximum weight over 50 tons (49 long tons; 55 short tons).

QuestionLight trucksare classifiedthis way because they are car-sized, yet in the U.S. they can be no more than 6,300 kg (13,900 lb). Theseare used bynot only used by individuals but also businesses as well. In the UK they may not weigh more than 3,500 kg (7,700 lb) andare authorizedto drive with a driving license for cars.Pickup trucks, popular in North America, are most seen in North America and some regions of Latin America, Asia, and Africa.Although Europe doesn't seem to follow this trend, where the size of the commercial vehicle is most often made as vans.
