How a motorcyclist maintains his position in a Death well?

Solution : At the uppermost point of the death well with no support from below the motorcyclist does not drop down This is because his weight is being balanced by the centrifugal force Infact the weight of the motorcyclist is spent up in providing the necessary centripetal force to the motorcyclist and hence he does …

How does a well of death work?

When you’re riding the Wall of Death the centrifugal force pushes you outwards and then friction holds you up. Imagine the wall was wet and slippery – you’d slide right down. That’s why it was very important that the wall was kept dry and free from dust and drops of oil.

Which force act in Death well?

The walls of death well are at rest. Here, the friction balances the weight of the person while reaction of the wall provides the centripetal force necessary for circular motion. The forces are shown in the figure.

What is meant by well of death?

What is the safest speed of a motion of a cyclist in a death well?

Minimum speed of biker should be 28 m/s such that friction will be sufficient to balance weight in y− direction.

What is Wall of Death motorcycle?

The Wall of Death has been the most enigmatic dare-devil motorbike stunt for more than 100 years. Motorcyclists ride around the inside of a vertical wall, rather like a huge barrel, at speeds of around 30mph. Most Wall of Death “drums” are about 32 feet (10 metres) in diameter.

What is sphere of death Class 12?

What are the different forces that acts on the motorcycle and the rider when performing the Wall of Death stunt?

These include the gravitational force, which acts downward from the bike to the walls, the frictional force that the walls exert against the tires of the bike, and the normal reaction force, a perpendicular push back by the wall surface when it receives a force.

What are the 4 stages of death?

Vass, a Senior Staff Scientist at Oak Ridge National Laboratory and Adjunct Associate Professor at the University of Tennessee in Forensic Anthropology, human decomposition begins around four minutes after a person dies and follows four stages: autolysis, bloat, active decay, and skeletonization.

What happen immediately after death?

Decomposition begins several minutes after death with a process called autolysis, or self-digestion. Soon after the heart stops beating, cells become deprived of oxygen, and their acidity increases as the toxic by-products of chemical reactions begin to accumulate inside them.

What happens at the time of death?

When someone is dying, their heartbeat and blood circulation slow down. The brain and organs receive less oxygen than they need and so work less well. In the days before death, people often begin to lose control of their breathing. It’s common for people to be very calm in the hours before they die.
