In the previous tutorial, we have discussed the list of Material Testing Methods, in this tutorial we are going to discuss how to conduct the tensile test. Tensile Test The tensile test comes under the destructive test where we apply the gradually increased load up to the material get fracture. So a tensile test is a static […]
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.
This is the art of Mechanical engineering.
The Idea Thake shape and eventually come to life
The components that we design and engineering should satisfy the service and the requirement. For that, engineers make sure that each type of material should be tested before we used for the making of the components. Along with the strength, there are other properties are also needs to test such as hardness, toughness, brittleness, etc. […]
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 […]
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 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 […]
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 […]
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 […]
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. […]
In Strength of materials, Fatigue refers to the failure of the machine component due to the repeated or cyclic loading. Due to the fluctuation in the stress, this failure occurs. Let’s discuss the Fatigue failure in briefly. Fatigue Failure Fatigue failure is defined as the brittle fractures occurred while a repeated load or cyclic 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 […]
From all the way, we have discussed the different types of stress and strains, Now its time to understand what are the principal stresses. The maximum stress induced in a plane is called the principal stress and the plane at which the maximum stress induced referred to the principal plane where the shear stress is […]
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 […]
Crane Hook Design Problem: The crane hook carries a load of 20 kN as shown in given below Fig. The section at X-X is rectangular whose horizontal side is 100 mm. Find the stresses in the inner and outer fibres, the given section. Solution: Given data (All are in Metric Units) Load (W) = 20kN […]
When we say common Cross-section properties, what we will think of? First of all Sectional area, Section modulus, the moment of inertia, and few other. The different cross-section properties for the different cross-sections such as circular, square, rectangular and trapezoidal and triangular are discussed briefly in this article. First of all, we have to understand […]
In material science, materials are classified into four groups Metals, Non-metals, Ceramics, Composites. In this article, we are going to discuss Non-Metallic Materials. The Non-Metallic materials are used in engineering due to their less density and flexibility, resistance to electricity, heat and most importantly it is available at low costs. Non-Metallic Materials Before going into the topic it […]
The metal which is consisting of the main constituent other than the iron is known as Non-ferrous metals. For example aluminium, copper, lead, nickel, tin, titanium and zinc. We have discussed the characteristics of the different Non-ferrous metals and the purpose and use of the non-ferrous metal in different applications in this article. Non-Ferrous Metals Having lightweight, high conductivity, corrosion resistance […]
Case Hardening is also known as Surface Hardening. Sometimes also are known as the Face Hardening. The process of hardening the surface of the components is known as the Case Hardening. There are different types of Case hardening processes available. We have discussed each of them here! Case Hardening / Surface Hardening The process of Hardening […]
In material science, the Heat treatment processes used to impart the physical properties by altering the microstructure. We have discussed the purpose of the heat treatment and the different heat treatment processes briefly. Heat Treatment Heat Treatment includes the heating and cooling of the metal to obtain the desired mechanical properties without changing the chemical […]
We all know Stainless steel is notable for its corrosion resistance property. Stainless steel is an alloy of iron and chromium which will significantly improve the corrosion resistance property. Along with the chromium, there are few other alloy elements to make the stainless steel more strengthen and harden and tough and increase the few other […]
Steel is the alloy of iron and carbon. Steel consists of carbon content up to a maximum of 1.5%(Somewhere it will be mentioned as up to 2%). The other elements of steel are silicon, phosphorous, manganese, copper etc. will be having the more or fewer compositions to attain the desired properties. In this following article, we are going […]
