Springs are used to store and release energy. They can be of various types and designs based on the application.

• Types of springs include compression, tension, torsion, and flat springs

• Design considerations include material selection, wire diameter, number of coils, and pitch

• For example, a compression spring used in a car suspension system would require a high spring rate and corrosion-resistant material

• A torsion spring...read more

Polymers are large molecules made up of repeating units called monomers. They have various types based on their structure and properties.

• Polymers are classified into three types: natural, synthetic, and semi-synthetic.

• Natural polymers are found in nature, such as proteins, DNA, and cellulose.

• Synthetic polymers are man-made, such as polyethylene, PVC, and nylon.

• Semi-synthetic polymers are derived from natural polymers, ...read more

Motors are devices that convert electrical energy into mechanical energy. There are various types of motors.

• DC motor

• AC motor

• Stepper motor

• Servo motor

• Brushless DC motor

• Linear motor

Coupling is a device used to connect two shafts together at their ends for transmitting power.

• Couplings are used to transmit torque from one shaft to another.

• They are used to compensate for misalignment between two shafts.

• Couplings can also be used to absorb shock and vibration.

• Examples of couplings include gear couplings, jaw couplings, and fluid couplings.

Clearance refers to the level of access granted to an individual for classified information or restricted areas.

• Clearance is granted by the government or an organization.

• There are different levels of clearance such as Confidential, Secret, and Top Secret.

• Clearance can be required for jobs in fields such as defense, intelligence, and government.

• Examples of clearance types include Personnel Security Clearance (PSC), Faci...read more
