this is small model of fourbar mechanism with is use in every ic engine for generating power. The simplest closed-chain movable linkage is a four-bar linkage, commonly known as a four bar mechanism. It comprises four bodies called bars or links joined in a loop by four joints. The joints are typically constructed, so the links travel in parallel planes, and the assembly is known as a planar four-bar linkage. There are also spherical and spatial four-bar links, which are employed in reality.The four bar mechanism is a type of mechanical linkage that is used in many different devices. There are several applications for four-bar systems in equipment. Typical applications will include:Locking pliersBicyclesOil well pumpsLoadersInternal combustion enginesCompressorsPantographs
