Two stroke engines complete a power cycle in two strokes of the piston, while four stroke engines complete it in four strokes.

• Two stroke engines have a simpler design and are lighter than four stroke engines.

• Two stroke engines have a higher power-to-weight ratio than four stroke engines.

• Four stroke engines are more fuel efficient and have a longer lifespan than two stroke engines.

• Examples of two stroke engines include chainsaws, dirt bikes, and jet skis, while examples of fou...read more

Petrol engine and diesel engine are two types of internal combustion engines that differ in their fuel ignition process.

• Petrol engines use spark plugs to ignite the fuel-air mixture, while diesel engines use compression to ignite the fuel

• Petrol engines are generally more powerful and responsive, while diesel engines are more fuel-efficient and have more torque

• Examples of petrol engines include those found in cars, motorcycles, and small aircraft, while diesel engines are comm...read more

Shock absorbers are devices that help to absorb and dampen shocks and vibrations.

• They are commonly used in vehicles to improve ride comfort and handling

• They work by converting kinetic energy into heat energy

• They consist of a piston and cylinder filled with hydraulic fluid

• The fluid is forced through small holes or valves to slow down the movement of the piston

• There are different types of shock absorbers, including twin-tube, monotube, and coilover

• Regular maintenance and replac...read more

Vibration is the back and forth movement of an object. It can be reduced by balancing, isolating, or damping.

• Balancing rotating equipment to reduce vibration

• Isolating vibrating equipment from surrounding structures

• Using damping materials to absorb vibration energy

Welding is a process of joining two materials together by melting them and allowing them to cool, creating a strong bond.

• There are several types of welding processes including MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), Stick, and Flux-Cored Arc Welding.

• Each type of welding process has its own advantages and is used for different applications.

• Welding can be done using different heat sources such as gas flames, electric arcs, lasers, or ultrasound.

• Common materials welded ...read more

A shock absorber is a mechanical or hydraulic device designed to absorb and dampen shock impulses.

• Shock absorbers are commonly used in vehicles to reduce the effects of bumps and vibrations on the suspension system.

• They work by converting kinetic energy into heat, which is then dissipated.

• Examples of shock absorber brands include Bilstein, Monroe, and KYB.

There are several types of shafts including straight, stepped, tapered, splined, and flexible.

• Straight shafts are the most common type and have a uniform diameter throughout their length.

• Stepped shafts have varying diameters at different sections.

• Tapered shafts have a gradually decreasing diameter from one end to the other.

• Splined shafts have ridges or teeth along their length to connect with other components.

• Flexible shafts are used in applications where a rigid shaft cannot...read more
