Basic Engineering Sciences and Economics

Study lessons

1. 1

   Engineering Economics

   Match every cash flow to its factor and depreciation method so interest, annuity, gradient, rate-of-return, and break-even items on the MELE math paper become fast, exact points.

   15 min
2. 2

   Statics, Equilibrium, and Friction

   Resolve forces, take moments, solve equilibrium of particles and rigid bodies, work trusses by joints, locate centroids, and handle dry friction with the standard SI formulas the MELE tests most.

3. 3

   Dynamics and Work-Energy

   Apply the kinematic equations, projectile motion, Newton's second law, the work-energy theorem, impulse and momentum, and rotational motion to solve MELE dynamics items exactly in SI units.

4. 4

   Strength of Materials

   Compute axial and thermal stress, torsional shear, beam bending stress and deflection, and combined loading with the standard SI formulas the MELE turns into fast, exact points.

5. 5

   Thermodynamics Fundamentals

   Use the ideal-gas law, the first and second laws, the standard processes, entropy, and the Carnot cycle to solve MELE thermodynamics items exactly in SI units.

6. 6

   Fluid Mechanics and Basic Sciences

   Use fluid properties, hydrostatic pressure, buoyancy, continuity, and Bernoulli's energy equation, plus core chemistry and physics facts, to solve the remaining MELE basic-science items exactly in SI units.
