single slider crank is a simple actuator which consists of four links and which converts rotary motion into reciprocating and vice versa.
Used for Oil Pumps and stuff.
In a single slider crank mechanism when one of its links is fixed it gives a motion in which one of d link is fixed, 2nd link acts as a crank which is connected to a piston (acts as a slider )an the piston is pivoted on the fixed link. As the crank rotates the piston reciprocates (piston is enclosed in a cylinder). At the other end of the cylinder (on which the fixed link is not connected) another link is connected at the end of which a cutting tool is fixed . There is a crank which is connected to a lever which had a shaft through it. As the crank is turned, the lever goes up and down. A pole can be connected to the lever with a fairy or whatever to show flight or whatever. A crank and slotted lever turns rotational motion into an up and down oscillating motion.
The theory of the Slider-crank mechanism is while the entire mechanism has six free degrees, the whole system only has one free degree. When those six degrees start moving, the whole thing can only move in circular motions.
Using a slider crank opposite to the conventional sense, (ie, input to the slider and output obtained at the crank) should do the job. This should help you : http://www.youtube.com/watch?v=PZO-BhkWIMM
Crank lengths are used because the moments at the edge strips are negative while that at mid span are positive so reinforcement are alternatively provided at the top and bottom respectively.. so just to have connection between the reinforcement and for the slab to behave as a single unit by providing continuous bars, cranking is done in slabs..
application of slider crank
the crank and slider mechanisme is cool
It is used for cranking the slider when you can not slide the crank.
There are four links in the slider crank mechanism.
Double slider crank mechanism is used where two slider works or the crank also work as a slider it uses to transform Reciprocating motion into rotary

The rotating part is called to be the crank and the piston which is made to move forword and backword is said to be the the slider. in case of automobiles the input energy or the valve motion of the slider rotates tehe crank as well and the force that has been supplied to the slider produces the torque on the crank which helps in the rotation of the wheel as aresult the vehical starts moving.The other examples are Reciprocating pumps, Reciprocating comprssor etc. And also in case of the Typewriter,Clocks etc, the force that has been suplied to the slider is unable to over come the friction of the crank and hence the force is utilise as much it is required
