Various types of brakes include disc brakes, drum brakes, regenerative brakes, electromagnetic brakes, and hydraulic brakes.

• Disc brakes use calipers to squeeze brake pads against a rotor to slow or stop the vehicle.

• Drum brakes use shoes that press against the inside of a drum to slow or stop the vehicle.

• Regenerative brakes convert kinetic energy into electrical energy to recharge the battery.

• Electromagnetic brakes use an electromagnetic field to create friction and slow or st...read more

Different types of fit include clearance fit, interference fit, and transition fit.

• Clearance fit: parts are designed to have a gap between them, allowing for easy assembly and disassembly.

• Interference fit: parts are designed to be pressed or forced together, creating a tight and secure fit.

• Transition fit: parts have a small amount of overlap, creating a balance between clearance and interference fit.

• Examples include piston and cylinder in an engine, bearings in a machine, and...read more
