Suppose you are in the elevator. What to do if you suddenly fall down the elevator?
ans:
Think of it, you will come down the elevator from the 8th floor of City Center, one of the tallest buildings in Bangladesh! After getting on the elevator on the 5th or 5th floor, he realized that his lift had been torn. I mean, now the elevator is taking you down freely. What to do in such a situation? Think? Call Someone? Looking for help? Press the emergency button? In fact, you will not have time to think about any of these things unless you have some idea in advance. Because one of the six cables in the elevator breaks, the other cables become obsolete. And every second the speed of the fall of the elevator increases. After four seconds, the lift will drop down to a speed of about 5 meters per second. Which is about 5 miles an hour. And at this speed the lift will take just 5 seconds to fall down from the floor of the city center! What do you do in just 5 seconds? You can't get enough time to panic in these six seconds without thinking or asking for help! But in these six seconds you can use the brain to calm down.
In the case of a lift accident, many people think that jumping in the elevator can be avoided or standing upright. We will try to understand a little scientifically whether it can actually be saved? So let's know, what does science say about what happens if you jump or stand?
What if you were standing?
The elevator started to tear up, as if someone was standing. In this case, when the elevator lifts him down, his weight will increase many times more than his normal weight. How is that Suppose his weight is 5kg and the elevator is going down at 5 meters per second. Then its velocity is 1x3 = 1 kg / m per second. And since gravitational acceleration is working on both him and the elevator, his speed will increase every second. And just when he falls down with this momentum, while standing, his body will be centered at a few points perpendicular to the load. Then he would think that someone was hitting his head at a lot of speed with something a lot more than his weight. As a result, the neck will be broken first and then the neck will slowly wrinkle. There is a possibility of death.What happens in the jump?First of all, what's the wrong idea about surviving the jump? When everyone jumps to keep himself in the elevator at zero or free, then the elevator will fall first and then he will not suffer as much. But the funny thing is, when someone jumps from the elevator to zero but the elevator doesn't jump, the elevator will continue to fall at the same speed. If he falls at the same speed, he will first be hit with the top of the elevator. Then he will have to return to the elevator floor again. When he returns to the elevator floor, his speed will increase and his body weight will increase several times. There is one more problem with jumping. You will understand this if you play long jumps or jumps as a kid. You need to apply some force to the ground to jump, the higher the ball, the higher we can apply. In that case, a ball is to be applied to the floor of the elevator to jump the lift, the amount of force being at least 1 newton or 5 kg.
The funny thing is that by applying this force to the floor to make the jump, the weight of the lift increases by 5kg, so the lift falls down faster. As a result, the amount of damage can be increased.So what to do?If you stand in the elevator, the amount of damage will increase, jump will increase! So what to do? This question is turning heads? Elliot H. Frank, a researcher at the Biomedical Center at MIT University, answered this question. He says lying in the elevator at the time of the accident is a safer method than lying to others. It seems to you that if you scream, you will have the same momentum, the weight will increase and multiply. So how come the safe haven? But Elliott also has a great scientific explanation. When someone is screaming, not all the weight will fall to a certain place because of the speed or excess weight that is spread throughout the body at different points. Rather, the injury will spread all over the body, thus reducing the severity of the injury. It does not have to stand or jump.
