From braking distances and falling objects to electricity and pressure, ignoring physical laws doesn’t stop them from working. Understanding even basic concepts helps you predict outcomes, avoid accidents, and make safer decisions. Physics isn’t optional — it’s always active. Awareness of forces + basic knowledge = better safety. Safety note:

Civil Engineering on Instagram: "20mm vs 10mm Aggregate — Which One Makes Stronger Concrete? Concrete ki strength sirf cement pe nahi… aggregate ke size par bhi depend karti hai. 10mm aggregate gives better workability and smooth finish, perfect for plastering, flooring, and tightly reinforced sections. 20mm aggregate improves strength, reduces cement consumption, and is ideal for RCC beams, columns, slabs, and foundations. In construction, choosing the right aggregate size—whether 20mm aggregat
