Machine defects refer to faults or imperfections in a machine that affect its performance or functionality.

• Machine defects can be caused by wear and tear, poor maintenance, or manufacturing errors.

• Examples of machine defects include broken parts, malfunctioning sensors, and software bugs.

• Identifying and addressing machine defects is crucial for ensuring product quality and safety.

Casting defects are imperfections in the final product caused during the casting process.

• Casting defects can include porosity, shrinkage, cold shuts, misruns, and inclusions.

• Porosity is caused by gas bubbles trapped in the metal during solidification.

• Shrinkage occurs when the metal contracts as it cools, leading to voids or cavities in the final product.

• Cold shuts happen when two portions of the metal do not fully fuse together during solidification.

• Misruns occur when the met...read more

Solar panels convert sunlight into electricity through the photovoltaic effect.

• Solar panels are made up of photovoltaic cells that absorb sunlight and convert it into direct current (DC) electricity.

• The DC electricity is then converted into alternating current (AC) electricity through an inverter.

• The electricity generated by solar panels can be used to power homes, businesses, and even entire cities.

• Solar panels require direct sunlight to generate electricity, so their effici...read more
