The 5 engine part names are piston, cylinder, crankshaft, camshaft, and valve.

• Piston: Moves up and down inside the cylinder to compress the fuel-air mixture.

• Cylinder: Houses the piston and allows for the combustion process.

• Crankshaft: Converts the linear motion of the piston into rotational motion.

• Camshaft: Controls the opening and closing of the engine's valves.

• Valve: Regulates the flow of fuel-air mixture and exhaust

1st and 3rd angle methods are used in engineering drawings to represent the orientation of an object in 3D space.

• 1st angle method is commonly used in Europe and Asia, while 3rd angle method is used in North America.

• In 1st angle method, the object is placed in the first quadrant of the viewing plane, while in 3rd angle method, it is placed in the third quadrant.

• The symbol for 1st angle projection is a square with a dot ...read more

Vernier caliper and micrometer are both precision measuring instruments, but they differ in their design and measurement range.

• Vernier caliper measures both internal and external dimensions with a range of 0-150mm or 0-6 inches.

• Micrometer measures thickness or outside dimensions with a range of 0-25mm or 0-1 inch.

• Vernier caliper uses a sliding scale and a vernier scale for measurement, while micrometer uses a screw mec...read more

PPM stands for parts per million. It is a unit of measurement used to express the concentration of a substance in a solution.

• PPM is calculated by dividing the number of parts of a substance by the total number of parts in the solution and multiplying by one million.

• Formula: PPM = (Number of parts of substance / Total number of parts in solution) * 1,000,000

• For example, if there are 10 parts of a substance in a solution...read more
