Q1. How calculate the weight of plates
Ans. 
The weight of plates can be calculated by multiplying the density of the material by the volume of the plate.
• Determine the density of the material the plate is made of (e.g. steel has a density of 7850 kg/m^3)

• Measure the dimensions of the plate (length, width, thickness)

• Calculate the volume of the plate using the formula: volume = length x width x thickness

• Multiply the volume by the density to get the weight of the pla

Q1. What is the casting solidification time?
Ans. 
Casting solidification time is the duration it takes for molten metal to solidify in a casting process.
• Casting solidification time depends on factors like material type, mold temperature, and casting geometry.

• Higher pouring temperatures generally result in shorter solidification times.

• Thicker sections of the casting will take longer to solidify compared to thinner sections.

• Aluminum alloys typically have shorter solidif
