Governor is a device used to maintain the speed of an engine within specified limits when the engine works in varying of different loads. Based on the source of controlling ..
The Grashof’s law states that for a four-bar linkage system, the sum of the shortest and longest link of a planar quadrilateral linkage is less than or equal ..
Degrees of freedom for planar linkages joined with common joints can be calculated through Gruebler’s equation. Gruebler’s equation is given by the formula: ..
Classification of gears can be done according to the relative position of the axes of revolution into three types. They are: Gears for Parallel shafts 1.1 Spur Gears ..
A belt is a looped strip of flexible material used to mechanically link two or more rotating shafts. A belt drive offers smooth transmission of power between shafts ..
In this article, on the first table, I have compared the differences between the mechanism and machine. On the second table, I have compared the differences between ..
Watt linkage is also known as the parallel linkage. James Watt invented Watt mechanical linkage. In Watt’s linkage central moving point of is constrained to travel ..
Some of the basic terminologies that every mechanical engineering student need to know are covered in this article. Acceleration: Acceleration is the time ..
In analyzing the motion of a machine or mechanism, it is often difficult to visualize the movement of the components in a full assembly drawing. So we need to use kinematic ..
In a sliding joint, contact force always acts perpendicular to the surface in contact. This contact force is commonly referred to as a normal force because it acts ..
The transformation of motion from one shaft to another shaft requires three bodies: a frame (the position of each shaft is fixed in the frame) and two gears. Consider ..
Slow forward and quick return mechanisms are to be found on some metal cutting machines, digital printing machines and digital scanners. The output gives ..
A cam is a rotating or sliding piece in a mechanical linkage that drives a mating component known as a follower. From a functional viewpoint, a cam-and-follower ..
Involute tooth profile is almost used generally everywhere and given preference over cycloidal tooth profile or any other gear tooth form. This doesn’t mean ..
