Math is used in engineering to design and build new components or products, maintain running components, and simulate real-life scenarios for testing and learning. In addition, it is necessary to construct and maintain structures. Every engineering discipline relies heavily on math, which is also frequently utilized in research.

Mathematics is a broad subject with numerous variations. Different types of arithmetic can be used in many engineering disciplines to arrive at a certain answer. In electrical engineering, for example, linear algebra is commonly used to design electrical circuits. Digital logic design, a critical component of computer construction, is based on Boolean algebra.

Later in this blog, you will learn about how do engineers use maths in different areas of engineering. Let us first start with civil and mechanical engineering and then industrial engineers.

**HOW DO ENGINEERS USE MATHS IN CIVIL AND MECHANICAL ENGINEERING?**

Geometry is utilized in civil and mechanical engineering to design structures and guarantee that they operate safely and effectively. Civil engineers may utilize differential equations to compute the approximate size of the supporting piers required while building a bridge. They may also employ sophisticated mathematical modeling to forecast the structure’s expected lifespan.

**HOW DO ENGINEERS USE MATHS IN INDUSTRIAL ENGINEERS?**

Calculus is used by industrial engineers to determine the pace at which specific variables in a particular process will change. To guarantee that all operations are adequately regulated, industrial engineers frequently make approximations and safe estimations. These approximations and estimations are based on one or more kinds of mathematics.

**HOW DO ENGINEERS USE MATHS IN PRACTICAL SOLUTIONS TO PROBLEMS?**

Let us take an example of one of the mechanical features in automotive industries that* the Braking System.*

Automobile engineers must design braking systems that behave in a predictable and desirable manner to assure motorist safety. They must also be able to design automobiles that meet specific safety requirements. To accomplish so, engineers must fine-tune a car’s braking force. The amount of power or pressure required to bring something to a complete stop is known as the braking force.

Calculate a car’s braking force. You must evaluate all of the mechanical and physical elements that are involved.

A CAR’S BRAKE FORCE CAN BE DETERMINED BY USING:

The torque of the wheels.

The rolling radius of a tire.

As a result, the computation for calculating braking force would look like this.

Brake force (kg) = Wheel torque (m-kgs)/(Tyre rolling radius(m)/12)

HOWEVER, YOU WILL NEED TO EXERCISE TO WORK OUT THE WHEEL TORQUE:

The friction force of the brake pads.

The effective radius of the rotor.

After that, it would be computed as.

Wheel torque (m-kgs) = (Brake pad friction force(kg))x(Rotor effective radius(m)/12)

BUT YOU MUST WORK OUT IN ORDER TO GET THE BRAKE PAD FRICTION.

The clamping force of the caliper.

The brake pad’s size is in millimeters.

After that, it would be computed as.

Brake pad friction force(kg) = (Calliper clamp force(kg))x(µ of the brake pad)

WHILE THE EFFECTIVE RADIUS OF THE ROTOR IS DETERMINED VIA.

The diameter of the rotor.

Diameter of the caliper piston.

Rotor effective radius(m) = [(0.5)(Rotor diameter (m))]-[(0.5)(Calliper piston diameter(m))]

**WHY ARE THESE CALCULATIONS SO IMPORTANT?**

While many auto technicians could tinker with car parts to make modifications to a car’s braking system. Engineers have a unique set of skills. Engineers use calculations like the one above to design the mechanical components and systems that mechanics work with. When engineers are creating or modifying anything, mathematics aids them in achieving absolute accuracy.

All engineering is built on the foundation of mathematics. Bridges would crumble under stress without it, lightbulbs would blow up every time you turned on a switch in your house, and automobile brakes would only function occasionally.

**FINAL WORDS.**

Despite the fact that computers can handle many arithmetic problems, engineers still require a strong mathematical foundation and a grasp of mathematical concepts. Not only do engineers use maths but it is an important part of engineering. Through this blog, we have tried to let you know about how do engineers use maths in different areas of engineering.

**FREQUENTLY ASKED QUESTIONS (FAQs)**

- What kind of math do engineers use?

Ans. Trigonometry, in addition to engineering geometry, is a common math subject for engineers. Engineers can compute data such as the height of an existing building, the measurement of an angle, or the distance between two locations using the trigonometry concept.

- Do engineers really use math?

Ans. However, the great majority of engineers who graduate will work in the industry. When you consider what they perform on a daily basis, you’ll notice that they need to be quite strong at algebra.
