CLUTCH
A clutch in machine elements connects and disconnects power transmission. The clutch engages/disengages the power transmission between the engine and gearbox. It allows gear shifts in manual transmissions. Clutch and Gearbox work together, but perform different jobs - Clutch: connects/disconnects the engine from the gearbox (like an on/off switch) - Gearbox: changes gear ratios for speed/torque adjustments (like a speed controller). Type of clutch 1. Friction clutches: - Engage/disengage via friction. Friction clutches include - Single plate clutch: common in cars - Multi-plate clutch: more torque, used in heavy vehicles/bikes - Cone clutch: older tech, less common - Wet clutch: oil-cooled (e.g., some bikes) - Dry clutch: no oil (e.g., most cars) 2. Dog clutches: - Engage/disengage via mechanical "jaws" or "teeth" - No slipping, direct power transfer - Used in: Manual transmissions (some), Racing cars, Industrial machinery 3. Electr...
