How to calculate impact load and impact force
Starting from the essence of black money,
the essence of black money is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique[ 8] In the metaphor of RMB, black money is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 22 million special solutions, so the upper limit of bitcoin is 22 million[ 8]
to mine the dark coin, you can download the special dark coin calculation tool, register various cooperative mine pool websites, fill the registered user name and password (miner user) into the calculation program, and then click the operation to officially start. After completing the installation of the darkcoin client, you can directly obtain a darkcoin address. When others pay, you only need to post the address to others, and you can pay through the same client. After installing the Black Coin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, the personal dark coin will be completely lost
RMB can also be electronic and more flexible than paper money. The central bank's digital currency is the electronic RMB, which is equivalent to paper money, but more flexible than paper money. It can also track your capital flow, and can pay without network
P = MV
I = ft = △ P
F can be calculated.
for example, when a bullet hits a wall at a speed of 400m / s, it takes 0.1s
P = 400m
F = P / T = 4000N
the momentum change of the object is Δ P = m (U-V), then the impulse is I = m (U-V), so the impulse is f = m (U-V) / T
where f, u and V are vectors.
first, the free falling time of 100 mm height:
t = (2 h / g) ^ 1 / 2
Second, the free falling speed of 100 mm height:
V = GT
third, the maximum bearing capacity of the test object at the moment = the weight of the weight of the code 25 kg * the free falling speed of 100 mm height / the impact time of the test object
landing needs to be calculated by momentum
ft = MV
impact force F = 57 * √ 20 / T
t is not given in this question, so the condition is insufficient Here t refers to the time when the collision moves to rest, not the time when it falls
the - 57n upstairs is obviously unreasonable. The 57kg object is still on the ground, and the force is more than that. You can think of a 57kg sandbag as a person, with almost the same weight. If this person jumps to a scale, it doesn't need 1m. It's estimated that if he jumps 10cm, he will find that the pointer of the scale will reach a large value quickly
hope to solve your problem.
