Dolly (tool)
A dolly is the name given to a category of tools used in shaping sheet metal. In general, a dolly is a solid piece of metal, small enough to hold in one hand, with a curved or shaped face. Generally a dolly will have more than one surface, each with its own radius of curvature (much like a three-dimensional French curve), allowing the craftsman more flexibility in using the tool.
A dolly can be used either as a hammer, shaping the metal to match the curve of the dolly, or as small anvil to provide a curved surface over which to dome or dish metal. They are commonly used to shape sheet metal in auto repair, especially in locations where it is difficult to swing a hammer.
They can also be used as backers for upsetting metal. When used as a portable anvil, a dolly can be used to hold a rivet in position while it is being clenched with a "snapper". Such dollies are commonly cylindrical in shape, and rely on mass to work. The act of using it is known as holding up or holding on. Dollies can also be used in boat building, when clenching nails. See clinker (boat building).
Tool
A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Tool use by humans dates back millions of years, and other animals are also known to employ simple tools.
Tools that are used in particular fields or activities may have different designations such as "instrument", "utensil", "implement", "machine", "device," or "apparatus". The set of tools needed to achieve a goal is "equipment". The knowledge of constructing, obtaining and using tools is technology.
History
Anthropologists believe that the use of tools was an important step in the evolution of mankind. Because tools are used extensively by both humans and wild chimpanzees, it is widely assumed that the first routine use of tools took place prior to the divergence between the two species. These early tools, however, were likely made of perishable materials such as sticks, or consisted of unmodified stones that cannot be distinguished from other stones as tools.
Stone artifacts only date back to about 2.5 million years ago. However, a 2010 study suggests the hominin species Australopithecus afarensis ate meat by carving animal carcasses with stone implements. This finding pushes back the earliest known use of stone tools among hominins to about 3.4 million years ago.
Programming tool
A programming tool or software development tool is a computer program that software developers use to create, debug, maintain, or otherwise support other programs and applications. The term usually refers to relatively simple programs, that can be combined together to accomplish a task, much as one might use multiple hand tools to fix a physical object. The ability to use a variety of tools productively is one hallmark of a skilled software engineer.
The most basic tools are a source code editor and a compiler or interpreter, which are used ubiquitously and continuously. Other tools are used more or less depending on the language, development methodology, and individual engineer, and are often used for a discrete task, like a debugger or profiler. Tools may be discrete programs, executed separately – often from the command line – or may be parts of a single large program, called an integrated development environment (IDE). In many cases, particularly for simpler use, simple ad hoc techniques are used instead of a tool, such as print debugging instead of using a debugger, manual timing (of overall program or section of code) instead of a profiler, or tracking bugs in a text file or spreadsheet instead of a bug tracking system.

Dolly (magazine)
DOLLY is a monthly teen magazine started in 1970 by Fairfax Ltd. in Australia and New Zealand, and purchased by ACP in 1988. The current editor is Lucy E Cousins. The previous editor was Tiffany Dunk.
Dolly was the basis and inspiration for Sassy Magazine (1987-1996) in the United States. The magazine is aimed at older teenage girls (13-17 age group) and covers celebrity news and gossip, fashion and beauty and various feature articles attractive to female teenagers and dealing with issues that are faced by this age group and gender. The magazine also has a website containing games, information on upcoming issues, quizzes and downloads. The magazine has now produced over 400 issues and as of 2007 has a readership of 505,000.
Controversy
In 2005, Dolly came into media attention for taking advantage of young people wanting to get into the magazine industry. Dolly was accused of soliciting, publishing and ridiculing unpaid articles from hopeful young women looking for a job in magazine journalism.
Dolly (trailer)
A dolly is an unpowered vehicle design for connection to a tractor, truck or prime mover vehicle with strong traction power.
Dolly Classification by Axle Configuration
There are two types of dolly bogie:
Full trailer - 2 axle (4 wheels), with a draw bar which also controls the trailer's front axle steering. The draw bar does not take load of the full trailer. Heavy full trailer needs to have its own brakes remotely controlled by the prime mover vehicle.
Semi-trailer - 1 axle (2 wheels), without the front axle but have a landing gear. Large semi-trailer of truck size is designed for connection via the fifth wheel on the tractor unit or the semi-trailer truck. Small semi-trailer such as travel trailer and boat trailer is design for connection via a tow hitch of a passenger vehicle. Either the fifth wheel or the tow hitch takes up to half to load of the semi-trailer.
Special large dolly bogie is equipped with a fifth wheel for further connection by the gooseneck type drawbar of another similar dolly and form a road train. The last dolly in a road train needs its own rear lights, brakes remotely controlled by the prime mover vehicle, and registration plate.
