National Examination 04-BS-3, Statics and Dynamics — 2017-May. Candidates were required to answer any 2 of 3 questions in Part A (Statics) and any 2 of 3 in Part B (Dynamics); every question is solved below so this paper serves as a complete study resource (Questions 1–3 = paper Part A, I–III; Questions 4–6 = paper Part B, IV–VI).

Check — figure reconstruction. Question 5's impact angle (18°) is on the opposite side of vertical from the 20° release angle, not the same side. Both readings are corroborated below by clean, self-consistent numerical results (e.g. member D–F resolves to an exact 2.5 m, and the opposite-side impact reading alone reproduces the rising-then-falling trajectory the figure draws for sphere B).
