Mechanisms with Lower Pairs topics include: Lower pairs mechanisms, extracting straight line motionwith sliding pair, straight line and steering gear mechanisms.
A lower pair is a pair where the connection between two elements is through the area of contact.
There are six types of lower pairs in spatial mechanisms: Spherical pair, Plane pair, Cylindrical pair, Revolute pair, Prismatic pair, Screw pair. A spherical pair is a kinematic pair where one element of the pair is spherical and turns inside the other stationary element. A higher pair is a kinematic pair in a mechanism that has two degrees of freedom (DOF). Higher pairs are more complex than lower pairs and involve non-contact interaction between elements.
Some examples of higher pairs include: A cylinder or sphere lying on a flat surface The relative motion of a cam and follower The point of contact between two involute gears meshing
