Civil Engineering Tutoring

Civil engineering is a wide degree. Most programs start everyone in the same place with statics, mechanics of materials, and fluid mechanics, then split into areas that each have their own course sequence and their own design codes. Structures, geotechnical, water resources, environmental, transportation, and construction all use different tools and different kinds of exam problems. It is normal to do well in one area and struggle in another. Sessions focus on whichever course is giving you trouble right now, and they use your own syllabus, homework, and exam dates rather than a fixed script.

STEM Tutor 360 offers one-on-one tutoring for each of these areas, and every area has its own page: structural analysis, steel design, reinforced concrete design, geotechnical engineering, hydraulics and hydrology, environmental engineering, transportation engineering, construction engineering, and surveying. The foundation courses have pages as well: statics, mechanics of materials, and fluid mechanics. If you are working toward licensure, the FE Civil and PE Civil exams have pages too. A free consultation is a good way to decide where to start.

A problem that crosses courses, worked

A simply supported beam spans 6 m and carries a uniform load of 10 kN/m. It has a rectangular section 200 mm wide and 400 mm deep. Find the maximum bending stress.

Statics gives the reactions: each support carries half of the total load, $\tfrac{10 \times 6}{2} = 30\ \text{kN}$. The maximum moment sits at midspan and equals $$\dfrac{wL^{2}}{8} = \dfrac{10 \times 6^{2}}{8} = 45\ \text{kN-m}$$

Mechanics of materials takes over from there. The section modulus is $$S = \dfrac{b h^{2}}{6} = \dfrac{200 \times 400^{2}}{6} = 5.33 \times 10^{6}\ \text{mm}^{3}$$ The maximum stress is $$\dfrac{M}{S} = \dfrac{45 \times 10^{6}\ \text{N-mm}}{5.33 \times 10^{6}\ \text{mm}^{3}} = 8.44\ \text{MPa}$$

One small problem used two foundation courses. Later it feeds structural analysis (deflection) and steel or concrete design (choosing a section that is strong enough). That chain is why civil courses build on each other so tightly.

Where students usually get stuck

• Weak statics habits, such as skipped free body diagrams, that cause trouble in every later course
• Unit mix-ups between kN and N, mm and m, or psf and ksf
• Treating design courses as formula lookup instead of learning the limit state behind each check
• Trying to learn the code book by reading it. It works better to solve problems and find each provision as you need it.
• Waiting until the week of the exam to start on the topics that feel unfamiliar
