What is Physics for Engineering?<\/h2>\n
When many students enroll in an engineering course, one of the first questions that arises is: Why study physics if I want to work in industry, management, or technology?<\/strong><\/p>\n The answer lies in the very role of physics in engineering: it is the foundation that allows us to understand, analyze, and solve real-world problems. More than just theory, physics functions as a practical tool used to design machines, improve processes, and ensure safety.<\/p>\n This question is common because, in high school, physics is usually presented in a very theoretical way, with a more introductory character. <\/p>\n The main goal of physics in high school is to present fundamental concepts, such as motion, force, energy, and electricity, in an accessible way.<\/p>\n The problems are generally simplified and the mathematics used is more basic, focused on the direct application of formulas. Furthermore, at this stage, the student's main objective is to pass a university entrance exam.<\/p>\n The story changes when the student enters an engineering course. Physics begins to play an important role in practical applications. These applications appear in different areas of engineering related to energy, machines, electronics, and industrial processes.<\/p>\n In this way, instead of simply solving exercises, the engineer uses the principles of physics to:<\/p>\n It's worth mentioning that in engineering, mathematics also becomes more complex with the use of differential and integral calculus. More recently, with technological advancements and the emergence of more robust computers, the use of Big Data tools (data analysis) has become more common.<\/p>\n Read also: <\/strong>Does Production Engineering involve a lot of calculations?<\/a><\/p>\n<\/blockquote>\n Below are some examples of how physics appears in the daily routine of different engineering activities.<\/p>\n The use of physics in industry stems from the fact that industrial machines obey the laws of mechanics. In this context, the engineer must understand how forces are transmitted in the different types of gears in machinery.<\/p>\n For example, let's consider a machine that needs to transport a certain weight. We know that, in this case, it's necessary to use Newton's laws to design the machine's motor to meet that objective.<\/p>\n Furthermore, this dimensioning should not only take into account the force, but also the torque (which is force times a distance) and the power of that motor. Additionally, it is possible to design the system in such a way that the rotational speed of the machinery's gears is increased.<\/p>\n Another activity that appears in engineering is the proper use of energy. It is worth remembering that, in physical phenomena, energy is always in transformation. For example, in high school, we study how, when an object falls from a certain height, gravitational potential energy is transformed into kinetic energy.<\/p>\n However, in an industrial operation, there is also energy transformation, but with losses. Unlike ideal examples, such as a falling object, some of the energy ends up being dissipated mainly in the form of heat. Physics allows us to identify these losses and proposes solutions to reduce them.<\/p>\n One example is the use of electric motors in industry. Part of the electrical energy received by these motors is not converted into useful work. This occurs because no motor achieves 100% efficiency, as established by the Laws of Thermodynamics. Therefore, it is up to the engineer to propose solutions to minimize these losses.<\/p>\n One alternative is to replace existing motors with more efficient machines or to optimize their use. Furthermore, factors such as lighting and cooling systems in the environment where these motors operate are also fundamental to improving the factory's energy consumption and reducing environmental impact.<\/p>\n Read also:<\/strong> What does a production engineer do? Find out what this career is like.<\/a><\/p>\n<\/blockquote>\n In high school, we use the concept of static equilibrium to calculate forces. In engineering, this concept is applied to the safety of industrial structures and equipment, as this safety depends on a proper analysis of the forces involved.<\/p>\n In a factory, whenever a material supports weight or is subjected to stress, it is necessary to verify whether it will withstand it without deforming or breaking. An example of this is the placement of heavy machinery in a factory. In this case, the engineer must perform calculations to ensure that the floor or structure where the equipment will be installed will support the load.<\/p>\n Another example is large warehouses and distribution centers, which have metal structures capable of supporting large volumes of products. Physics is used to calculate the internal forces of these structures, ensuring that they can safely support all this weight.<\/p>\n Thermodynamics aims to study the concepts of temperature, heat, and the different types of transformations associated with temperature changes.<\/p>\n These concepts are widely used in industry, as there are various heating and cooling systems at different stages of production. Therefore, proper temperature control is fundamental to ensuring production quality and process efficiency.<\/p>\n One example of the use of thermodynamics is industrial furnaces, which reach extremely high temperatures. They are used in a variety of applications ranging from the ceramics industry to metallurgy.<\/p>\n On the other hand, there are also refrigeration systems that need to keep substances at very low temperatures. In this context, engineers must know how to control these temperatures to preserve the properties of the materials processed in these systems.<\/p>\n Thermodynamics is also present in energy generation. One example is thermal power plants, in which heat generation is responsible for the production of electrical energy, which can be used for industrial purposes.<\/p>\n The production engineer will use physical concepts as a tool in industry to improve processes, reduce costs, maximize production, and increase the efficiency of production systems.<\/p>\n In practice, we can apply the examples mentioned above:<\/p>\n Read also:<\/strong> What are the 7 types of engineering?<\/a><\/p>\n<\/blockquote>\n We have shown that physics has various applications in the field of engineering, because more than just a set of formulas, physics should be understood as a tool that enhances the engineer's ability to analyze situations, propose solutions, and innovate.<\/p>\n In this way, knowledge in Physics enhances professional opportunities, making the engineer better prepared to work in different contexts, both technological and societal.<\/p>\n Do you want to become a production engineer and understand more about physics?<\/em><\/strong> How Does Physics Appear in an Engineer's Daily Routine? *Written by: Ricardo Noboru Igarashi, Professor of Production Engineering at ESEG College.
