A machine part subjected to an axial compressive force is called a strut. A strut may be horizontal, inclined, or even vertical. But a vertical strut is known as a column, pillar, or stanchion. The machine members that must be investigated for column action are piston rods, valve push rods, connecting rods, screw jack, side links of toggle jack, etc. In […]
In Mechanical Engineering, Machine Design is subjected to creating new or Advanced machines. This involves improving the existing machines to better machines.
The design process is a time-consuming process which includes implementing an Idea and considering the commercial and economic aspects, Making the idea into a shape in the form of drawings by keeping the available resources in mind to make the actual Idea into a life.
What is Rankine’s Formula for Columns?
Usually, it is a common phenomenon observed in long columns failure due to buckling load and the short columns usually fail due to crushing load. The Rankine-Gordon formula assumes a combined failure mode which is combined buckling and crushing loads in columns. This common mode is known as the Rankine formula for columns. Hence, we […]
What is Euler’s Column Theory?
A machine part subjected to a vertical axial compressive force is called a column. it is also known as a pillar or stanchion. We see this vertical axial compressive force such as piston rods, valve push rods, connecting rods, screw jack, side links of toggle jack, etc. The first rational attempt, to study the stability of long columns, […]

Procedure for Designing Rocker’s Arm for Exhaust Valve
A rocker’s arm is a valvetrain component that typically transfers the motion of a push rod to the corresponding intake/exhaust valve. The rocker’s arm is used to actuate the inlet and exhaust valve motion as directed by the cam and follower. Let us see if we can design Rocker’s Arm for Exhaust Valve for a petrol […]
Find stiffness of the spring in Hartnell Governor
Hartnell Governor is basically a Centrifugal governor with a spring-loaded weight instead of dead weight on the sleeve to increase the speed of the balls required to lift the sleeve on the spindle. The Bell crank Lever holds two dead-weight balls for a Hartnell governor in order to regulate the fuel flow for the engines […]
How to Design a Bell Crank Lever?
The Bell crank lever consists of two arms at right angles. Such types of levers are used in railway signaling, governors of Hartnell type, the drive for the air pump of condensers, etc. Let us design a simple Bell Crank Lever for one of these applications. In the previous articles, we have discussed different Mechanical […]
How to Design a Lever Safety Valve?
A Mechanical Lever is a rigid rod or bar capable of turning about a fixed point called a fulcrum. It is used as a machine to lift a load by the application of a small effort. Lever Safety Valve is used to maintain a constant safe pressure inside the boiler. When the pressure inside the boiler increases the […]

A Mechanical Lever is a rigid rod or bar capable of turning about a fixed point called a fulcrum. It is used as a machine to lift a load by the application of a small effort. Let us discuss more on how we can design a Lever for any application you have. History of Lever […]
What is Forging? | Classification of Forging
Forging is a process of deforming the metals and alloys into desired and specific shapes by the application of repeated blows from a hammer. Forging can be done either while the metal or the alloy is hot condition or sometimes forging can be done when the metals are in cold condition. Let us discuss more […]
Why Hollow Shaft is better than a Solid shaft?
Have you ever wondered why most of the time you have seen many applications involve hollow shafts instead of solid ones? How the Hollow Shaft is better than a Solid shaft? Let us see how the hollow shafts are better than the solid ones. Differentiating the Hollow shaft and solid shaft can be done with […]
How to Calculate Shaft Diameter under Axial Load?
In the previous article, We have discussed how to calculate the shaft diameter under twisting and bending moment with the fluctuating load. In some cases such as propeller shafts of ships, there will be an additional axial load that will act on the shaft in addition to the Torsion and bending loads. Now let us […]
Torsional Rigidity vs Lateral Rigidity
Torsional Rigidity is simply the resistance to the angular twist of any shaft or beam. But how it is different from Lateral Rigidity? Let us discuss Torsional Rigidity and Lateral Rigidity in detail to understand the differences. In the previous articles, we have been discussing how to design a shaft if it is subjected to […]
Example Problem on Calculating Shaft Diameter
In the previous articles we have discussed calculating shaft diameter if it is subjected to twisting moment, bending moment, fluctuating, and Axial Load. Following are the list of all the article we have discussed. How to calculate the shaft diameter from the torque? How to calculate Shaft Diameter under Twisting, Bending Moment, and Fluctuating? How […]
How to calculate Shaft Diameter under Twisting and Bending Moment?
In the previous article, we have discussed that from a given torque we can calculate the shaft diameter, but what if the shaft is subjected to the bending moment and twisting at the same time? Let us see how we can calculate shaft diameter under the twisting and bending moment. Design of Shafts The design […]
Turnbuckle: Adjustable Screwed Joint for Round Rods
A turnbuckle is a joint or also known as a coupling to join two threaded rods together. This turnbuckle is also referred to as Rigging screws or an Adjustable Screwed Joint for Round Rods. Let us see how we can design Turnbuckle to connect two threaded rods. Turnbuckle In this adjustable screwed joint, one of […]
Design Calculations of Knuckle Joint
A knuckle joint is a mechanical joint that helps to connect two rods that are under the action of tensile loads. In some cases, it is possible to join the rods with knuckle join if they are under compressive load with proper guided supports. In this article, we will discuss how to calculate the design […]
