TranslateMechanical Engineering
Motion, forces, machines, gears, and how things move.
Lessons
All lessonsFundamentals of Interference Fits
Mastering the mechanical precision of securing components using internal stress and thermal expansion.
Understanding Structural Integrity: The Power of Triangles
Explore why the triangle is the most stable shape in engineering.
Friction and Motion: The Mechanics of Surfaces
Learn how friction helps or hinders mechanical movement in machines.
Levers: The Ultimate Force Multipliers
Learn how mechanical engineers use levers to move heavy things with ease.
Gear Ratios Explained
Discover how different gear sizes allow us to trade speed for power.
Challenges
Kinematic Constraint Analysis: The Passive Gripper Challenge
Design and construct a purely mechanical, passive-actuation end effector capable of grasping three distinct objects of varying geometry and mass using only gravity or a single linear displacement input. Your solution must demonstrate a clear grasp of underactuated linkage synthesis and force closure principles while maintaining a structural mass under 500 grams. Evaluated based on cycle reliability, grip stability under a 2G acceleration load, and the integration of a compliant transmission mechanism.
Sketch a machine in your home
Find any machine or mechanism in your home (a can opener, a door lock, scissors, a lamp switch, a stapler). Sketch how you think it works on the inside — label the parts and the forces. You don't need to be right; you need to think like an engineer. Submit a photo of your sketch and a short explanation.
