Dimensioned drawing of a slider-crank (left) and its kinematic diagram (right). In mechanical engineering, a kinematic diagram or kinematic scheme (also called a joint map or skeleton diagram) illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as ...
For example, a 40" pulley at 100 rpm would turn a 20" pulley at 200 rpm. Pulleys solidly attached ("fast") to the shaft could be combined with adjacent pulleys that turned freely ("loose") on the shaft (idlers). In this configuration the belt could be maneuvered onto the idler to stop power transmission or onto the solid pulley to convey the power.
On this drawing the displacement changes from figure to figure. Work done (work = force * distance) is the same in each case, the weight is always 100 N and always lifted 10 cm, and the product of the rope displacement and force is always the same (100 N * 10 cm, 50 N * 20 cm, etc.) -- atropos235 ( blah blah , my past ) 00:32, 25 March 2008 ...
The idler arm supports the end of the center link on the passenger's side of the vehicle. The idler arm bolts to the vehicle's frame or subframe. Generally, an idler arm is attached between the opposite side of the center link from the Pitman arm and the vehicle's frame to hold the center link at the proper height. Idler arms are generally more ...
[12] Diagram 3 shows that now three rope parts support the load W which means the tension in the rope is W/3. Thus, the mechanical advantage is three. By adding a pulley to the fixed block of a gun tackle the direction of the pulling force is reversed though the mechanical advantage remains the same, Diagram 3a. This is an example of the Luff ...

An idler gear is a gear wheel that is inserted between two or more other gear wheels. The purpose of an idler gear can be two-fold. Firstly, the idler gear will change the direction of rotation of the output shaft. Secondly, an idler gear can assist to reduce the size of the input/output gears whilst maintaining the spacing of the shafts.
Assembly drawings detail how certain component parts are assembled. [2] An assembly drawing shows which order the product is put together, showing all the parts as if they were stretched out. This will help a welder to understand how the product will go together so he get an idea of where the weld is needed. The assembly drawing will contain ...
