One example would be the construction of bridges and overpasses. Engineers need to consider the expansion and contraction of the materials used, such as concrete and steel, due to temperature changes throughout the year. Failure to account for these changes could result in structural damage or failure of the bridge due to excessive stress on the materials.

What is the importance of mathematics in engineering?
Engineers need to calculate the exact number of bricks, cement, metal or other materials to be used in making the skycrapers or any other building so as to minimize the cost of buying the materials!
What has the same expansion rate as steel?
nothing, like people: each material is different. steel... " talking about mild steel here" has an expansion rate of 0.06 - 0.07 times the lengh for every 100 kelvins this rule holds true up to 1173 kelvin, this is known as a terminal point as the steel starts to soften and alter its physical state thare are other materials avalable with very similar expansion rates bt as a general rule of thumb, each metalic molacule is specific to its (ER)
What is the meaning of function in mathematics?
You can imagine a machine that can manufacture some given materials and then can output the materials(of course the materials themselves doesn't change)in some other shapes.That is what a function in mathematics do.You give a point or a number for f(x),then you will get y,which y=f(x).Take f(x)=5x,for example ,if you make x=2,then you will get y=10.you can imagine that the function make a change for the number you put. Actually,when we learn further about Mathematics ,we doesn't take much consideration on the definition of a function but the properties of it such as differentiation .also ,you can define the function as a map.Here ,I'm giving you some intuitive explains,hope it will help you!
How is math used to build builsings?
Yes, definitely - cannot do it without math - actually, cannot do much of anything without math You use math by solving algebra equations developed by engineers relating to strength of materials. Those equations are in college level courses, but you need to know basic algebra to solve them - also some calculus, and definitely geometry and trigonometry.
What is thermosetting materials?
Thermosetting materials fuse under heat. The change is usually permanent.
Examples of uses of the expansion and contraction of materials?
insoulble
What are some ways expansion and contraction could cause safety hazards?
If memory serves me, expansion and contraction can cause stress cracks in many materials, due to breakdown of molecules in the material.
Could expansion or contraction cause problems?
Yes, expansion or contraction of materials can cause problems in structures, particularly if they are not accommodated for in the design. If expansion or contraction occurs unevenly or is not properly controlled, it can lead to issues such as warping, cracking, or failure of the structure. Proper planning and use of materials that can accommodate thermal expansion and contraction is important to avoid these problems.
What is a thermal actuator?
A thermal actuator is a mechanical system that uses thermally induced contraction and expansion of materials to create motion. It basically converts energy into motion.
Why does expansion cause serious problems for engineers?
Expansion can cause serious problems for engineers because it can lead to the distortion or misalignment of components and structures. The differential expansion between different materials can create stress and strain, leading to fatigue and failure of the components. It is crucial for engineers to consider expansion and incorporate proper design techniques, material selection, and allowances for thermal expansion to mitigate these problems.
What can result from the Expansion and Contraction of objects?
If two materials with different coefficients of expansion are held together (by rivets glue or some other means) and subjected to changing temperatures the resultant stress might cause one or the other or both to fail (break).
What do materials engineers do?
Material Engineers bring valuable expertise in materials from mining to recycling. The job of a Material engineer is to produce, design and evaluate materials and their use.
Which is more stressful on materials cooling or heating?
Not exactly sure what you mean by "stressful"...Cooling causes an object to contract and heating causes an object to expand. The amount of contraction/expansion depends on the situation.
What kinds of materials do engineers use to build walls?
There are many types of materials engineers use to build walls. Three possible construction materials are wood, brick, and concrete.
Do engineers study cars?
There are many types of engineers such as:aerospace engineers,canal engineers,chemical engineers,civil engineers,electrical engineers,environmental engineers,genetic engineers,industrial engineers,materials engineers,mechanical engineers,structural engineers,systems engineers,just to name a few.Some of which do study cars.
What type of scientist is knowledgeable about materials?
Chemists and engineers. Surface chemists and materials engineers spring to mind.... but there's a lot of different materials so they don't all lie in any strict areas.
What is thermal expansion and contraction?
when your feet go in shoes and then your feet expand and contract so your shoes will not fit.
