Plate 1 Finals

This document contains instructions for completing two plates of civil engineering problems related to simple and compound curves. For each plate, students are directed to write their name and section, copy problems, show step-by-step solutions with labeled diagrams, sign each page, follow instructions to avoid penalties, and submit on time. Plate 1 contains 5 sample problems testing skills like determining middle ordinate, stationing of points of intersection, and radius of a compound curve. Plate 2 instructs students to compose and solve 10 additional problems each for simple and compound curves.
