2 stroke engines have a power stroke in each revolution, while 4 stroke engines have a power stroke in every other revolution.

• 2 stroke engines have a simpler design and are lighter than 4 stroke engines.

• 2 stroke engines have a higher power-to-weight ratio compared to 4 stroke engines.

• 4 stroke engines are more fuel-efficient and produce less pollution than 2 stroke engines.

• Examples of 2 stroke engines include chainsaws, motorcycles, and outboard motors, while examples of 4 str...read more

The Extrude command in SOLIDWORKS is used to create a 3D solid or surface by extending a 2D sketch in a specific direction.

• Extrude is a fundamental feature in SOLIDWORKS used for creating solid models.

• It allows you to add or remove material from a sketch to create a 3D shape.

• The command offers options for specifying the direction, depth, and other parameters of the extrusion.

• You can extrude a sketch symmetrically, asymmetrically, or up to a selected surface.

• Examples: creating...read more

Cable continuity can be checked using a multimeter to measure resistance and ensure that there is a continuous path for electrical current.

• Use a multimeter set to the resistance mode

• Connect one probe to one end of the cable and the other probe to the other end

• If the multimeter shows a low resistance reading (close to zero), it indicates good continuity

• If the multimeter shows a high resistance reading (infinite or very high value), it indicates a break or open circuit in the c...read more

Motor converts electrical energy into mechanical energy. It starts by applying a voltage to the motor windings.

• Motor converts electrical energy into mechanical energy

• Motor starts by applying a voltage to the motor windings

• Motor working principle involves the interaction between magnetic fields and current flow

• Different types of motors include DC motors, AC motors, and stepper motors

There are various types of welding processes such as MIG, TIG, Stick, Flux-cored, and Submerged Arc Welding.

• MIG (Metal Inert Gas) welding uses a wire electrode and a shielding gas to join two metal pieces together.

• TIG (Tungsten Inert Gas) welding uses a tungsten electrode and a shielding gas to create a high-quality weld.

• Stick welding uses a consumable electrode coated in flux to create a strong bond between two metal pieces.

• Flux-cored welding uses a wire electrode with a flu...read more

Press machines are used to shape and form materials by applying pressure.

• Hydraulic press: uses hydraulic cylinders to generate force

• Mechanical press: uses a flywheel and clutch to generate force

• Pneumatic press: uses compressed air to generate force

• Arbor press: used for light press work

• C-frame press: used for high force press work

• H-frame press: used for heavy-duty press work

AC (Alternating Current) and DC (Direct Current) are two types of electrical current used in various applications.

• AC changes direction periodically, while DC flows in one direction.

• AC is commonly used in household power supplies (e.g., wall outlets).

• DC is used in batteries and electronic devices (e.g., smartphones).

• AC can be easily transformed to different voltages, making it efficient for long-distance transmission.

• DC is more efficient for low-voltage applications and is use...read more
