There are several types of gears including spur, helical, bevel, worm, rack and pinion, and planetary gears.
Spur gears have straight teeth and are the most common type of gear.
Helical gears have angled teeth for smoother and quieter operation.
Bevel gears have cone-shaped teeth and are used to change the direction of rotation.
Worm gears have a screw-like appearance and are used for high reduction ratios.
Rack and pinion ...
Bearings are used to reduce friction between moving parts and support loads in various mechanical systems.
Bearings reduce friction between moving parts, allowing for smooth rotation or linear motion.
They support loads by distributing the weight evenly across the bearing surface.
Bearings can be found in a wide range of applications, from automotive engines to industrial machinery.
Common types of bearings include ball be

Java solves machine dependency by using bytecode and virtual machine.
Java code is compiled into bytecode which is platform-independent
The bytecode is executed by the Java Virtual Machine (JVM) which is platform-specific
JVM translates bytecode into machine code for the specific platform
This allows Java code to run on any platform with a JVM installed
Example: A Java program compiled on Windows can run on Linux or Mac as
