Mechanical Engineering Principles
Forces, materials, motion and the parts that transmit them
Every robot is a mechanical object before it is an electrical one. This track covers what holds a structure up, what makes it bend or break, and how force and motion are moved from a motor to the thing you actually want to move.
Statics, Materials and Motion
Moments, stress, gears and friction
- Statics & MomentsFreeWhy a structure stays still, how to find the force in a support, and the lever arm that decides everything.14 min
- Stress, Strain & StiffnessFreeWhy a part fails, the difference between strong and stiff, and why doubling a beam's depth is worth eight times as much as widening it.14 min
- Gears, Torque & AdvantageFreeTrading speed for force, why a motor alone rarely does the job, and how to pick a ratio.13 min
- Friction, Bearings & WearFreeThe losses that decide whether a mechanism runs sweetly or seizes, and how to choose what a shaft turns in.13 min
