Q2. There are two types of pase, AC and DC .
Ans. 
AC stands for alternating current, which changes direction periodically. DC stands for direct current, which flows in one direction consistently.
• AC is commonly used in household appliances and power distribution systems.

• DC is commonly used in batteries and electronic devices.

• AC can be easily converted to DC using a rectifier.

• Examples of AC sources include power outlets and generators.

• Examples of DC sources include batt

Q1. How waveforms on sheet metal can be measured
Ans. 
Waveforms on sheet metal can be measured using various techniques such as strain gauges, laser scanning, and ultrasonic testing.
• Strain gauges can be attached to the sheet metal to measure the deformation caused by the waveforms.

• Laser scanning can be used to create a 3D model of the sheet metal and analyze the waveform patterns.

• Ultrasonic testing can be used to detect any defects or irregularities in the sheet metal cau...read more

Q2. Difference between flatness and surface roughness
Ans. 
Flatness refers to the deviation of a surface from a perfect plane, while surface roughness refers to the texture of the surface.
• Flatness is a measure of how level a surface is, while surface roughness is a measure of how bumpy or irregular the surface is.

• Flatness is typically measured using a straightedge or surface plate, while surface roughness is measured using instruments like profilometers or roughness testers.

Q3. Allowable tolerances on casting surface
Ans. 
Allowable tolerances on casting surface depend on the application and material used.
• Tolerances are specified in engineering drawings and depend on the casting process and material used.

• Surface roughness, dimensional accuracy, and shape deviation are important factors to consider.

• Tolerances can range from +/- 0.1 mm to +/- 5 mm depending on the application.

• For example, a casting used in a high-precision aerospace applic...read more

Q4. Allowable tolerances on machining surface
Ans. 
Allowable tolerances on machining surface depend on the specific application and material being machined.
• Tolerances can range from +/- 0.001 inches to +/- 0.010 inches depending on the application.

• Materials with higher hardness or brittleness may require tighter tolerances.

• Surface finish requirements may also impact allowable tolerances.

• Consulting industry standards and customer specifications is important to determine
