I've just published an article on Mathematical Modelling of Engineering Problems, with title : Two Phase Heat Transfer on Porous Media Base Termite Nest Structure with Finite Element Method. We worked on Modeling heat transfer on Termite Nest Structure. Termites have a unique heat regulation where termite nests can maintain a stable temperature even though the temperature outside the nest changes. The termite nest itself has a porous structure that causes the temperature to move with a certain mechanism. The temperature in termite nests is considered to move through two phases, namely the conduction phase and the convection phase. The purpose of this research is to build a thermal insulation model and numerical analysis of thermal insulation models. The thermal insulation model in termite nests is made with a porous media approach. The article can be accessed on https://lnkd.in/gNM9jzGC. Thanks for the teams Nn Nastangini, Sri Nur Chasanah, and Aisyah Andria Rahman Raharjo.

Excited to share lab report on Free Vibration! In this experiment, I explored the natural frequency of a spring-mass system by observing its free vibration response. Using springs of varying stiffness and masses ranging from 0.5 kg to 2 kg, I measured the period of oscillation to determine the experimental natural frequency. The results closely matched theoretical predictions, with an error range of just 5-10%. Key findings: * Heavier masses reduce the natural frequency. * Stiffer springs increase the natural frequency. * Experimental results validated theoretical models, demonstrating the critical principles of free vibration in engineering. This research has important applications in fields such as civil engineering, automotive design, and aerospace, where understanding vibrational behavior is crucial for safety and efficiency. Check out the full report for detailed insights and data. #VibrationAnalysis #MechanicalEngineering #STEM #LabReport

Principle of Moments The principle of moments, also known as Varignon's theorem, is a fundamental concept in physics and engineering that describes the equilibrium of a rigid body under the influence of external forces. The principle states that the moment of a force about a point is equal to the sum of the moments of the components of the force about the same point. The moment is calculated by multiplying the magnitude of the force by the perpendicular distance from the point of application to the point about which the moment is being calculated. Consider a valve where a hand wheel is mounted on a pipeline. When someone applies a force to rotate the wheel, the moment of the force about the center can be determined by multiplying the magnitude of the force by the perpendicular distance from the center to the point of the force application. However, the calculation can become more complex if the applied force is not perpendicular to the valve or has multiple components. In this case, we can resolve the force into its component vectors and calculate each component's moment individually by multiplying it by the perpendicular distance from the point of application of that component to the point about which the moment is being calculated. Once each of the moments has been calculated, we can sum them up to determine the overall moment of the force about the point in question. The principle of moments can be used in a wide range of applications, from structural engineering to mechanical design. By calculating the moments of the forces acting on a system or structure, we can determine whether it is in equilibrium or whether it will rotate or move due to an imbalance of forces.

What is the difference between mass moment of inertia and simple moment of inertia? In engineering and physics, the terms "mass moment of inertia" and "simple moment of inertia" are often used interchangeably, but the context in which they are used can sometimes lead to confusion. Let's clarify the differences between these terms: Moment of Inertia: This is a property of a rigid body that describes how its mass is distributed around an axis of rotation. It quantifies the resistance of an object to changes in its rotational motion. There are two main types of moment of inertia: Mass Moment of Inertia: This is also known as the rotational inertia. It is a measure of an object's resistance to changes in its rotational motion around a particular axis due to its mass distribution. The mass moment of inertia is calculated based on the mass of the object and the distance of each particle of mass from the axis of rotation. It has units of kg·m² or slug·ft² in the International System of Units (SI) and the U.S. customary units, respectively. Area Moment of Inertia: This is also known as the second moment of area. It is a property of a shape that describes how its area is distributed around a given axis. The area moment of inertia is used in structural engineering and mechanics to calculate the stiffness and deflection of beams and other structures. It has units of m⁴ or in⁴, depending on the system of units. Simple Moment of Inertia: This term is not commonly used in technical contexts and may refer to the moment of inertia of a simple geometric shape, such as a rectangle, circle, or cylinder. These shapes have well-defined formulas for calculating their moments of inertia based on their dimensions and axis of rotation. The term "simple moment of inertia" may be used informally to refer to these basic calculations, but it is not a standard term in engineering or physics. In summary, the key distinction lies in the fact that "mass moment of inertia" specifically refers to the rotational inertia of an object due to its mass distribution, while "simple moment of inertia" may be a colloquial term referring to the moments of inertia of basic geometric shapes. ~Copied from QURA
