ENGINEERING MECHANICS
Mechanics this science is defined as a branch whose condition describes and predicts Body or body movement under powerful operation the engineering mechanism applies Principle for design, taking into consideration the principles of military effectiveness. Static Static’s are associated with the balance of the body. Hard body A strict body is defined as a certain amount of substance, the portion of which has been fixed The physical body is never completely related to each other, but it is quite rare Under the load's proceedings. If the deformation is negligible if compared to its size the body is called strict. Forced Persistent can be defined as any action that prompts someone to change the state of rest or movement. To whom it is applicable To define the full force, the required three numbers are called its S.
Solid
power / point load Distributed power action force is in the direction, with a
straight line through its direction of direction this app is used to move the
boat to the body when applied. This is the line the line of power called the
action. Power representation A straight line segment can be shown with a power
The composition of two armies There is a possibility of a reduction in the
system of armed systems for the armed forces There is a problem of designing
the equivalent forces Law of parallel If the α angle working under the angle AB
and A.C. If two lines are used A body at point A. Their actions are
characterized by the equivalent of a force's action Vector A.D., obtained as a
diagonal of a parallelogram constructed on a vector Directed as shown in Figure AB and
AC.
Determining
a force Changing one force by multiple factors Power action and feedback Often
physical condition controls are checked in the position of arms Free body
figure Checking the balance of the body requires free body head or While
drawing the free body figure And reactor on it Collin Force Balancing
:Equilibrium Law: The two forces will be balanced only they are the same
Slightness, vomit towards and velocity slider Determining a force Many factors
change the same-force Power action Using a parallelogram, a force rocks two
parts in R And the question one point is nice Balanced Equilibrium Balance
:Equilibrium laws: The balance of two armies can be only when they are big size
,Inverted and executed towards.
Abortive
act Make a positive form unsuccessful The forces in the Equilibrium deposit or
deduct from other systems Equilibrium of concurrent power in the plane If a
body is called equilibrium, it is done in many contradictory ways, Flat
parties, then these forces or their free speakers, when Has been geographically
added This system shows a balance status for any system Plane equivalent Lime’s
theorem While the three coordinated forces themselves are working, each power
Between the lines of the other two armies and continuously between the lines
Authentication is the same The principle of a power transmissibility: Using a
force, the inequality of the point can be transmitted with its linear action
Changing power effect on any rigid ladder Moment of Mode A moment of strength in
the context of a point: It is to think of feathers as the same force is under
two forces P and Q It is clear that strength p questions can be more effective,
even if they are Equal magnitude The power related effectiveness is the
tendency of rotation creation Body of a body That point moment = magnitude of
power * line spacing of the action line Of power Point is the center of the
moments of the moment and is perpendicular to the distance Hand the moment
called One unit is nm Vergon's theorem: Two concurrent forces in the context of
one of them centers in the moment The Arabic mathematical calculator of the
plane is the same Some centers.
Fraction
The force which opposes the agitation is called power Friction power or just
friction is a resistance to this speed The contact surface was offered by
micro-particles but, here There is a limit beyond If the applicable limit is
greater than this limit, Fresh power has a limited value when it is faster than
others That is happening, it is said to be the limiter Whenever the power is
applied, when the limited components are reduced, the body will appear
Relaxation and eg bone strength are called Static fractures, which are No value
during zero and limited fracture If applied, the force of the force exceeds the
friction limit, the body starts Other body and watch resistant resistance
Starting the protocol.
Experimentally it has been found that the
volume of volume is one big size There are two pages and these responses
consistently respond to general responses Francine is called multiplier
Friction multiplier = FN Where F is Fraction Limit and N is a normal reaction
in the contact surface Fractioning coefficient for showing μ.· Dynamic Freison is classified into the following two
types: A) Straight Depreciation) Rolling Fraction Sarita friction is friction
Other body Rolling friction is tightness Surface·Limiting friction
Fraction
Rule 1. Deprecated power works towards the body's reversal Moving Balance2. The
limit value is not equal to, the maximum of the power generation Forward-power
Obesity of limited friction the two pages of contact are called feedback and
this ratio is coefficientFraction's4. Deprecated power depends on the intensity
/ severity of this surface.5. Low power is the subject of two contacts Surface
6. The body starts It is less than its platform and it is stable Ratio with
normal ratio is called the ratio coefficient French angle Think of the horizon
surface and accordingly Horizon bridge p. The heat energy and N normal reaction
Therefore, the surfaces of the face are F and N, so they can be combined
drawing The properties for R function for normal response in R con θ. It is
given in the name of the con named θ.

angle 27 The angle elsewhere in the plane are formed With arrows, when the θ is
small, the block will rest on the plane. If θ is mild then Growth, comes with a
stage profit the θ, which is moving upward, is called the angle of the
resurrection. So much, the maximum The temptation of the plane, which is a body
free from the external body, gives rest When one strength runs towards P
Friction power limits friction and resultant response RK Caps with normal α
limited If a person has a dynamic movement in other movements, then the
resultant Usually giving the direction of the reactions, the distribution angle
limits to α. Thus, when the direction of the power varies through 360-B
Therefore, they create uniform quantitative cones in the middle and mid-center
of 'α'. Center of gravity At the center of gravity: This point is that of
distributed Gravity Power pass Due to the result of the body's gravitational
(weight) efficiency as a result of which At the center: A field is located in
the center of gravity.
