Q5. What is nominal stress for a mild steel plate
Ans. 
The nominal stress for mild steel plate depends on the thickness of the plate and the yield strength of the steel.
• Nominal stress is the maximum stress that a material can withstand before it fails

• For mild steel, the nominal stress is typically calculated using the yield strength of the steel

• The thickness of the plate also plays a role in determining the nominal stress

• The formula for calculating nominal stress is: Nomin...read more

Q9. How does solar module work
Ans. 
Solar modules convert sunlight into electricity using photovoltaic cells.
• Photovoltaic cells absorb sunlight and release electrons, creating a flow of electricity.

• The electricity generated by the cells is direct current (DC), which is converted to alternating current (AC) by an inverter.

• The AC electricity is then used to power homes, businesses, and other electrical devices.

• Solar modules can be installed on rooftops, in...read more
