Mechanisms (engineering) - Topics

Cobot safety: ISO TS 15066 and the force limits for a robot beside a person Adaptive automation: letting the machine decide when to hand control back Teleoperation latency: how much delay before an operator stops feeling in control Three Mile Island and a control room design that hid the real problem Why does one wheel spin when the other is stuck in an open differential? Planetary gear sets: where do three ratios come from one carrier? AR-15 vs AK-47 reliability claims: what the mud tests actually measure Haptic feedback in surgical robots: what a surgeon loses without touch Timing belt vs chain vs gear train: which is quietest at high rpm? Over-centre toggle clamps: what makes them hold with no power? Compliant mechanisms bend instead of hinging so they cannot seize or need oil How does an escapement turn a falling weight into a steady tick? Why do universal joints have to run in pairs to be smooth? Mode confusion in glass cockpits: how AF447 pilots lost track of what the aircraft was doing Where does lost motion hide in a bell crank and push rod linkage? How do you get straight-line motion out of a four-bar linkage? Why does a cam follower wear on the flank and not at the nose? Where is the wheel and axle on a bicycle: the crank or the hub? How do you clear the register on a Curta mechanical calculator? Spinning wheel ratios: what 6:1 does to your treadling Where do you measure backlash in a gear train and how much is too much? Vibration shaker fixtures that resonate at the wrong frequency Ball screw versus lead screw: efficiency and backlash in a linear axis Preload in a bearing pair: why too tight fails sooner than too loose What slips first in a worm gearbox pushed past its rated torque? Ratchet vs sprag clutch: which survives a back-driving load? How does a Geneva wheel give a film projector its intermittent motion?
