Gears are mechanical components that transmit motion and power between rotating shafts.

• Gears are toothed wheels that mesh together to transmit motion.

• They are used to change the speed, torque, and direction of rotation in machinery.

• Common types of gears include spur gears, helical gears, bevel gears, and worm gears.

• Gears are often used in vehicles, industrial machinery, and household appliances.

Yes, inventory cost includes GST.

• Inventory cost includes the cost of goods as well as any taxes paid on those goods.

• GST is a tax on goods and services, so it is included in the inventory cost.

• The amount of GST included in the inventory cost depends on the rate of GST applicable to the goods.

• For example, if the GST rate is 18%, and the cost of goods is Rs. 100, the inventory cost would be Rs. 118.

SOM deals with the study of internal stresses and forces in materials and structures.

• Study of internal stresses and forces in materials and structures

• Analysis of how materials and structures behave under different loads

• Designing structures to ensure they can withstand expected loads

• Commonly used in civil engineering and mechanical engineering

Mild steel has a linear stress-strain curve until it reaches its yield point.

• Mild steel has a yield point of around 250 MPa.

• After the yield point, the curve becomes non-linear and the steel undergoes plastic deformation.

• The ultimate tensile strength of mild steel is around 400-550 MPa.

• The fracture point of mild steel is around 20-25% strain.

• The stress-strain curve of mild steel can be used to determine its mechanical properties.

QC tools are used to ensure quality of products. Types include statistical process control, Pareto charts, fishbone diagrams, and more.

• Statistical process control (SPC)

• Pareto charts

• Fishbone diagrams

• Control charts

• Histograms

• Scatter diagrams

• Check sheets

• Flowcharts

• Cause-and-effect diagrams

• Six Sigma

• Lean manufacturing

Color coding is used to identify the resistance value of a resistor.

• The first band represents the first digit of the resistance value.

• The second band represents the second digit of the resistance value.

• The third band represents the multiplier.

• The fourth band represents the tolerance.

• For example, a resistor with brown, black, red, and gold bands has a resistance value of 1.0 ohm with a tolerance of +/- 5%.

NAPS Claim & BOAT Claim are two different types of claims under the National Apprenticeship Promotion Scheme.

• NAPS Claim is a claim made by the employer for reimbursement of the cost incurred on providing training to the apprentice.

• BOAT Claim is a claim made by the apprentice for the stipend amount due to them during the training period.

• Both claims are processed by the Board of Apprenticeship Training (BOAT) under the Ministry of Education.

• NAPS Claim covers the cost of basic t...read more

Screw threads and pitch distance

• Screw threads are helical ridges on a cylindrical surface.

• Pitch distance is the distance between two adjacent threads.

• Threads can be classified as coarse or fine based on their pitch distance.

• The pitch distance is measured in millimeters or inches.

• The pitch distance determines the tightness of the fit between the screw and the nut.

• Threads can be external or internal depending on whether they are on the outside or inside of the screw.

• Examples of...read more
