These stairs of a new building in Rochester, USA, designed by architect Rafael Nelson Tagalog Aboganda make everyone scratch their brains rattled. How is this possible??
Motorcycle engines work the same way that car engines do. They consist of pistons, a cylinder block and a head, which contains the valve train. The pistons move up and down in the cylinder block, driven by explosions of a fuel-air mixture that has been ignited by a spark. Valves open and close to allow the fuel-air mixture to enter the combustion chamber. As the pistons move up and down, they turn a crankshaft, which transforms the energy from the pistons into rotary motion. The rotational force of the crankshaft is transmitted, via the transmission, to the rear wheel of the motorcycle.
On this magnificent gif you can see how big Earth is and how there planets around Earth are big. This is an amazing fact which many people don’t know. We all need to know where we live and to know at least something about our Earth. Under the gif you can see all Earth fact, Polar Radius, Equatorial Radius, Mean Radius, etc.
The Earth has:-
Polar Radius: 6,356.8 km (3,950 miles)
Equatorial Radius: 6,378.1 km (3,963 miles)
Mean Radius: 6,371 km (3,958.75 miles)
Mean diameter: 12,742 km (7,917.5 miles)
Equatorial circumference: 40,075.02 km (24,901.24 miles)
Surface area: 510,072,000 km2 (196,939,900 miles)
Volume: 1.0832073 × 1012 km3
Mass: 5.9736 × 1024 kg
The diameter of the earth at the equator is 7,926.41 miles (12,756.32 kilometers).
One men from Boston made one really most bizarre pen ever, 3D Pen. His pen design can write a plastic words or numbers in the air. Words, numbers or everything else instantly freezes and like that yo can made some shape of hard plastic and that plastic retainers in its shape. This pen is like all others, normal, but it can draws a plastic and three-dimensional empty space.
