Is there any regulation that standardized the pipe diameter and thickness for the steam pressure? Yes, there is a regulation in India called the Indian Boiler Regulation, in short IBR which is created on 15th September 1950 to regularise the manufacturing of boilers, steam generators, and steam distribution piping systems. For the manufacturers and the […]
How to design a Hydraulic Press?
Have you ever wondered how to design a Hydraulic Press?? We use Hydraulic Press for many applications from a manufacturing point of view to compacting. In this article, we will understand how to design a hydraulic press by finding out the necessary parameter such as the diameter of the ram, vertical columns, and Hydraulic cylinder […]
How to design a Cylinder?
Have you ever wondered how to design a Cylinder?? I mean how the basic parameters such as diameter and thickness are set. We mostly see Cylinders in Internal combustion Engines, Compressors, and Hydraulic pumps. In all these cases the Cylinder will experience internal pressure caused by combustion in engines, air compressed by the piston in […]
Stresses in a Thin Cylindrical Shell
You must have seen heavy vehicles transporting fluids such as water/petroleum or steam boilers in some industrial plants etc. with a cylindrical structure called tanks or Pressure vessels. These Pressure vessels are used to store the fluids under the pressure. Since these fluids are stored under pressure, these may undergo a state of change inside […]
What is Section Modulus?
Section Modulus is also referred to as the Polar Modulus or the Torsional Sectional Modulus. It is denoted by Zp. Along with these, there are two more definitions also there to discuss. So let’s discuss this topic in more detail. (FYI: We discuss this topic more in terms of circular shafts, If you are looking […]
What is a shafts misalignment? |Causes|Effects|
When two equipment (Driver and driven) need to coupled together, then they need to be aligned properly to couple together. Installing the two equipment with 100% alignments is not possible. These misalignments can be accommodated by the special member called coupling. There are two different types of couplings. Flexible couplings and rigid couplings. These coupling […]
What are the different Flexible Coupling types?
A shaft coupling is a mechanical element that connects the two shafts together to transmit the torque from one end to the other by accommodating the misalignment. In the previous article, we have discussed the Functional requirement of coupling, coupling classification, and Rigid Coupling types. In this article, we are going to discuss the different Flexible […]
What are the different Rigid couplings?
In the previous article, we have discussed the Functional requirement of coupling and the coupling classification. In this article, we are going to discuss the different types of Rigid couplings. Rigid couplings Rigid Couplings are used to connect two shafts which are perfectly aligned. Following are the different types of rigid couplings. Sleeve coupling Muff […]
What is Shaft coupling? Different types of Coupling?
A shaft coupling is a mechanical element that connects the two shafts together to transmit the torque from one end to the other by accommodating the misalignment. Usually of a shaft can be made up of limited lengths so we have to make a couple multiple pieces of shafts to achieve the larger lengths to […]
How Compression Test is conducted?
In the previous tutorial, we have discussed the list of Material Testing Methods, and how to conduct the Tensile test, in this tutorial we are going to discuss how to conduct the Compression test. Compression Test The Compression test is also similar to the tensile test, the way we conduct it on the UTM. It also comes under the destructive […]
Design of Key for shaft in Machine Design
In the Previous article, we have discussed different types of keys for shafts, Now we are going to discuss what are the different types of forces acting on Key, and the design of Key for the shaft. Different forces acting on the Keys First of all, we have to know what are the different types of […]
What are the different types of Keys in machine design?
In mechanical engineering, Key is a part of a machine or equipment where it is used to connect the rotating machine element to the shaft and enables the torque transmission. In this article, we are going to discuss what are the different types of Keys in machine design. What is a Key? As we said above […]
What is Notch Sensitivity?
What exactly the notch sensitivity means? From our previous article, we have discussed how a fillet or a notch or a hole can reduce the stress concentration. But in this case, it will look somewhat different. actually, due to the presence of the notch or a hole in the body, the body tends to have […]
What are the Methods of Reducing Stress Concentration?
We have discussed how the stress concentration effect the different cross-section mechanical components. Due to the irregular stress distribution, stress concentration increases and let the component failure. So how we can reduce the stress concentration? There are few methods of reducing stress concentration. Methods of reducing stress concentration Before getting into the topic we have to […]
What is Stress Concentration? How to reduce it?
We have been seeing the shafts with the different cross-sections. What would really happen when a mechanical component has a different cross-section? Would it affect the stress distribution in the component? Yes exactly. Let’s see how the irregular stress distribution results in stress concentration. Stress Concentration Stress concentration occurs due to the irregular stress distribution. This irregular stress […]
Difference between Fatigue Limit and Endurance Limit
As we discussed earlier What is fatigue failure. The Fatigue refers to the failure of the machine component due to the repeated or cyclic loading. Whereas the fatigue strength or fatigue limit or Endurance limit is used to describe the material property that the cyclic load can be applied to the material without causing the failure. […]
What are the various Theories of Failure under static load?
Prediction of the failure of the machine component in the case of the uniaxial stresses(Simple tension or compression) is very simple by understanding the Stress-strain curve. Predicting the failure of any machine component is complicated when the machine component is subjected to the different types of Bi-axial stresses(Component subjected to two different stresses) or Tri-axial […]
What are the different Casting processes?
In the previous article, we have discussed what are the different manufacturing processes. The manufacturing process turns the raw material into finished products. There are different manufacturing process which uses different technologies and machinery to get the final products from the raw material. In this article, we discussed the different casting processes. Casting Processes Casting […]
