This document outlines a course on machine elements and mechanisms. The course objectives are to analyze machine motion, design simple mechanisms, and analyze static and dynamic forces in machines. Students will complete plates, quizzes, a group design project, and exams. The group project involves designing and building a remote controlled walking robot. Course materials will cover topics like linkages, instant centers, position analysis, velocity analysis, and acceleration analysis.

Course Information and Outline .
Course Title Machine Elements 1 (Laboratory)
Course Code ME 313 L
Description This course deals the analysis of the mobility, position, velocity, and
acceleration of common mechanisms using graphical, analytical
and computer-aided techniques. It also covers mechanism design
and; analysis of static and dynamic forces in mechanisms.
Course Objective At the end of the course, the students are expected to

method.
2. Design simple mechanisms moving in a prescribed fashion
3. Analyze static and dynamic forces in machines
4. Work harmoniously with team members playing different
roles
Requirements Plates. Plates will be done individually and will consist of drafting
exercises done inside the classroom or laboratory.
Quizzes. Quizzes are given after accomplishing one significant
topic. It shall consist of application and design problems. It may

1 Orientation
Introduction to Kinematics
Assignment # 1: Kinematic Diagrams (Individual)
Submit at least five (5) sketches of scaled machine part using
systems of links and draw its kinematic diagram. Discuss in
detail the main function of the machine and the behavior of the
motion, whether translation, rotation or combination of both.
Prepare to discuss your machine part next meeting. Use
pencil and A4 size paper.

Four-bar linkage
Assignment #2: Four-bar linkages (Individual)
Submit in one (1) Sintra board, models of four-bar linkages
specifically:
(1) Parallel-Crank Four-Bar Linkage
