CELE Engineering Mechanics — FrictionSlides
Friction slides, sized for screen and print. Flip through them for a five-minute pre-mock refresh, or print the deck for on-paper annotation. Either way, the slides cover Friction at the depth Professional Regulation Commission (PRC) — Board of Civil Engineering tests for the CELE 2026.
Exam context
For the Civil Engineer Licensure Examination, Professional Regulation Commission (PRC) — Board of Civil Engineering tests Engineering Mechanics under a "Core" label, with Friction in the 5th slot across 8 chapters. CELE candidates must clear the 70% weighted average, no sub-test below 50% cut on the 2026 paper, which draws about a meaningful share of Engineering Mechanics questions. Date to watch: May and November 2026.
