Mining dynamic map of Zhongli mine
is that ok
These days, in the original God, because of the new role of Zhong Li online, caused the attention of many players. Especially in the intensity of the clock, many players have a great doubt about the intensity of the clock. The reason is that Zhong Li's general attack and rate are too low, resulting in injury scraping. But there are also players who don't agree with Zhong Liqiang. Among them, one of the up main game crayons specially took the zero life clock to do the evaluation, in order to explain the intensity of clock, but it was questioned
Generally speaking, the way that up proves Zhong Li's strength is really impressive, and it also shows that Zhong Li has a strong applicability, and players can cultivate according to their own situationThe ever-increasing rhythm of clock departure is graally getting out of hand in the debate among players. In the face of growing public opinion dilemma, the original God of the official recently for the first time publicly responded to the clock from the rhythm of the relevant issues. This response did not give the players a reassurance, but let more players begin to question what was the original intention of the birth of qizhongli
However, in the official apology letter of the original God, they also said that they would give every character a stage to play their role in the future version. This also means that in the future world of the original God, there will be a suitable with a high degree of fit between the stage and the clock. Therefore, it seems too early to make an assertion on the intensity of clock departure at presentI, mechanics
Hooke's Law:
F
=
KX
(x is the elongation or compression; X is the compression; X is the elongation; X is the compression; X is the elongation; X is the compression; K is the stiffness coefficient, which is only related to the original length, thickness and material of the spring)
gravity:
G
=
mg
(g varies with the height above the ground, latitude and geological structure; Gravity is approximately equal to the earth's gravity on the ground)
3
to find the resultant force of F: use the parallelogram rule.
note: (1)
the composition and decomposition of forces follow the parallelogram rule.
(2)
the resultant force range of two forces:
F1-F2
F
F1
+
F2
(3)
the resultant force can be greater than or less than the component force, It can also be equal to the component force.
4, two equilibrium conditions:
the equilibrium condition of the body under the action of the copoint force: the body at rest or moving in a uniform straight line, the external force is zero.
fhe = 0
or
:
FX = 0
FY = 0
inference: [1] if three nonparallel forces act on the body and are balanced, then the three forces must be in common.
[2] three copoint forces act on the body and are balanced, The resultant force of any two forces and the third force must be equivalent to each other in reverse direction
(2
) the equilibrium condition of a body with a fixed rotation axis: the algebraic sum of the moments is zero. (only need to know)
moment: m = FL
(L is the arm of force, which is the vertical distance from the rotation axis to the action line of the force)
5, Friction formula:
(1)
sliding friction:
F =
FN
description
:
①
FN is the elastic force between contact surfaces, which can be greater than G; It can also be equal to g; It can also be less than g
②
is the sliding friction coefficient, which is only related to the material and roughness of the contact surface, and has nothing to do with the size of the contact area, the relative movement speed of the contact surface and the positive pressure n.
(2)
static friction: its size is related to other forces,
is solved by the equilibrium condition of the object or Newton's second law, It is not proportional to the positive pressure.
size range:
o
fstatic
FM
(FM is the maximum static friction, which is related to the positive pressure)
Description:
a
, the friction can be in the same direction as the motion, or in the opposite direction.
b, the friction can do positive work, negative work, or no work.
C, The direction of friction is opposite to the direction of relative motion or the trend of relative motion between objects.
D: static objects can be affected by sliding friction, while moving objects can be affected by static friction
