Mystery SOLVED - How did they Walk the Moai statues?
The Moai statues on Easter Island were transported a remarkable 13 km by the Rapanui people. These statues literally walked even though they didn't have legs. The mechanics behind this motion are nothing short of genius.
Consider this Moai statue. Imagine this statue is pivoted at one point. If you pull this edge backward, the other end of the Moai statue will move forward. Now by...

How are Bridges Built over the Ocean?
Please take a look at the foundations of a modern bridge. How are such gigantic foundations built? Especially when they stand on long concrete piles. Remember, the foundation is half submerged. To construct the foundation, engineers first need to install a watertight chamber, a caisson.
Let's observe the installation of this massive structure. Can you spot a major issue in this installation?...

Tesla Valve | The complete physics
A few commonly-used one way valves are shown here. All these valves have one thing in common: they all have moving parts. Here is a design challenge—is it possible to design a one-way valve without any moving parts?
Most of us will feel like this is an impossible design challenge, but not for design genius Nikola Tesla. Nikola Tesla has developed a one-way valve without any moving parts. In his...

Statue of Liberty : Even Today's Engineers are Surprised!
One of the biggest non-nuclear explosions in history, the Black Tom explosion, caused significant damages to the Statue of Liberty, but couldn’t topple it. The statue's strong iron frame is connected to the copper skin by these flat bars. Interestingly the flat bars are capable of flexing. What will happen in this design if a strong force acts on the copper skin? You can see the flat bars are bending. These flexible bars act like spring isolators and the force...

How are Modern Flyovers Built?
In this beautiful flyover, there are a few high-tension steel tendons protected in conduits. Unfortunately, they are corroding. Can you guess the impact of this on the flyover after 3–4 months? Why is this happening?
You may not believe this, but modern flyovers use these kinds of empty box girders for construction. Interestingly, the smart engineering of these girders allows male–female...

8 Things you should NEVER DO when driving an AUTOMATIC CAR
At first, driving a car with an automatic transmission may seem simpler compared to a manual transmission, in fact the controls of this type of gearbox are intuitive and useful in different situations, such as traffic where you stop and start again after a few seconds, or even on an uphill road. But even if it may seem like a basic type of transmission, there are some things you need to know.

Tesla Turbine | The interesting physics behind it
The maverick engineer Nikola Tesla made his contribution in the mechanical engineering field too. Look at one of his favorite inventions — a bladeless turbine, or Tesla Turbine. The Tesla turbine had a simple, unique design, yet it was able to beat the efficiency levels of steam turbines at that time. Normal turbines are complex in design, with blades of complicated geometry and stator parts. Nikola Tesla once said the Tesla turbine is his favorite invention and he even claimed...
