What Is Rivets : A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite to the head is called the tail.

What Is Taper Turning : Taper turning is the turning process in which the cutting tool moves at an angle to the axis of the workpiece so that a tapered shape is obtained in the workpiece. In a tapered piece, the diameter of the workpiece changes uniformly from one end to another. The workpiece can be tapered from inside or outside. To create taper the workpiece must be installed in such a way that the axis of rotation is at an angle to the axis of turning.

Inversion of Double Slider Crank Mechanism : Double slider crank shaft has two sliding pairs and two turning pairs. It is named Double Slider Crank Shaft because it has two sliding pairs. It has two sliders, one frame in which the slider moves and one link which connects the two slide and fix the distance between the two slider.The frame in which the sliders move is a combination of two straight grooves which form a single link and cut each other at right angle.

Watt Governor : Watt governor is the simplest and gravity controlled form of the centrifugal governors. It consists of two fly balls attached to the sleeve of negligible mass. The upper sides of arms are pivoted so that its balls can move upward and downward as they revolve with a vertical spindl.

https://mechanicaljungle.com/open-belt-drive-and-cross-belt-drive/ f-grinding-machine/ Parts and Functions of Grinding Machine]] :Grinding Machines or Grinders are tools which are used for grinding work pieces. It produces a smooth finish on flat surface. A grinding wheel is used in grinding machines for cutting. Grinding wheel is coated with abrasive material . Each grain of abrasive materials cut a small piece of workpiece via shear deformation.There are different types of grinding machines based on purposes.

Simple Indexing in Milling Machine : Milling operations sometimes, require the rotation of job correct to fractions of minutes, for each groove, slot etc., to be cut evenly on the job surface. The accuracy of spacing of teeth is very important particularly when the work is of precision character e.g., gear teeth, shafts, cutter teeth etc.

Open Belt Drive And Cross Belt Drive : Mechanical power transmission system takes help of several drives and elements in order to transmit power, torque and motion from one shaft to another shaft. Such drives can be either engagement type (gear drive and chain drive) or friction type (belt drive and rope drive). Belt drive is one reliable mechanical power transmission system that is commonly used to transmit power and motion over considerably larger distance (even up to 15m) between driving shaft (usually a prime mover such as an electric motor) to driven shaft. Being a friction drive, belt drive is inherently associated with slip.

Difference Between Girder and Beam : All structural materials for reinforced concrete and the standard acceptance tests for such materials are prescribed under the ACI (American Concrete Institute) Code which is a leading authority for inspection, project management and consulting for individuals and organizations involved in construction and concrete design.

Application of Cotter Joint : A cotter joint, also known as a socket and spigot joint, is a method of temporarily joining two coaxial rods. One rod is fitted with a spigot, which fits inside a socket on one end of the other rod. Slots in the socket and the spigot align so that a cotter can be ins erted to lock the two rods together.
Types of Riveted Joints : Depending on the how riveted plates are placed, the riveting classified mainly in to two i) Lap joint ii) Butt joint

Lap joint: In lap joint, plates overlapped each other. The rivets are inserted in the overlapped region.
Principle of Autocollimator : Autocollimator is an optical instrument that is used to measure small angular differences. This device is very sensitive to change in angles and provides a very accurate measurement of angular differences. It is basically a combination of an infinity telescope and a collimator. Autocollimators are mainly used to align optical components and measure optical and mechanical deflections.

Refrigeration System :Created in 2019, the World Refrigeration Day has the purpose of raising awareness among the international community on the role of HVAC-R in society. For centuries, humanity depended exclusively on nature to generate cold. From the underground systems for food and beverages preservation, made of terracotta rings by the chinese emperor Shih Huang Ti (220 B.C), to the ice farms .

Vertical Boiler : It consists of a cylindrical shell. This shell is usually placed in a vertical position. A popular boiler of this type has got the capacity of generating 300 kg of steam/hr. Its working pressure goes up to 10 bar.

Hydraulic Braking System :The sort of driving scheme used before the hydraulic braking system was mechanical driving scheme, so now the issue arises if we already have mechanical braking system so why hydraulic braking scheme? Just let's figure out.

Scotch Yoke Mechanism : Pirani Gauge is a device that is used to measure pressure, especially in vacuum systems. It was invented by a German physicist Marcello Stefano Pirani in the year 1906. It is based on a hot metal wire suspended in a tube and exposed to gas pressure media. This hot metal wire is made up of thin Tungsten, Nickel, or Platinum wire.

Pirani Gauge : Input torque balancing through addition of an auxiliary mechanism is a well-known way to improve the dynamic behavior of mechanisms. One of the more efficient methods used to solve this problem is creating a cam-spring mechanism. However, the use of a cam mechanism is not always possible or desirable because of the wear effect due to the contact stresses and high friction between the roller and the cam.

Flame in Gas Welding : In this gas welding flame, oxygen and acetylene are released at a one-to-one ratio. That is, an equal amount of oxygen and acetylene is released. It absorbs additional oxygen from the air as it provides complete combustion. A neutral flame is fine, clear, and well-defined. It is generally preferred for welding. it produces a luminous cone indicating the completion of the flame.
