SIMPLE AIRCRAFT
Many people assume that just
Physical science which
only naturalize without any
implementation. Mainly there are still many people who think that the only
study physics formulas. And not a few who do
not realize that many of the
events even things that are very close to us involves
the science of Physics. Even Physics is the
basic science that is needed by the
other branches of sciences.
Why Physics is
very important in our lives? Of
course as many of the events
in our lives that involve science Physics whether
we realize it or tan.pa we realize. The more we
understand the physics we find that physics has
a wide coverage.
Have you ever noticed when you want to move a stone mason big? For simplicity they sometimes use a stick / iron crowbar as a lever. The principle works is to put the foundation on the crowbar in between a rock and a hand.

The lever is one of the simplest types of aircraft that can be used to facilitate business. This is made possible by the existence of a lift-shaft (lever) with the fulcrum, the point style and point its location varied. Examples of the use of the principle of the lever is a crowbar. Now, the lever has been developed into a variety of tools that are useful in everyday life. How often have you cut your nails? Nail scissors tool is one tool that uses the principle of the lever.
The formula underlying
the work of the lever
is mathematically written:
Lb B x = F x lk
with:
• B = load
• F = force power
• lb = arm load (the distance between the load point to the fulcrum
• lk = power arm (the distance between the power of the fulcrum)
The conclusion of the above
formula is:
·
The longer arm of the power,
the smaller the value of force powers. This
means that the force that must be
spent to lift the load a little more.
·
The longer arm of the (lk)
greater mechanical advantage,
making it easier to do business
Example Problem:
A stone weighing 500 N is moved with a lever that is 3 m. To create a system of levers, used a rock as a footstool. If the distance of the point
fulcrum to the load 1 m, determine the force required to move the rocks!
A stone weighing 500 N is moved with a lever that is 3 m. To create a system of levers, used a rock as a footstool. If the distance of the point
fulcrum to the load 1 m, determine the force required to move the rocks!
Solution:
Know: answer:
Lever lenght= 3m
w x lb
lb = 1m
F = ______
lk = 3m -1m = 2m
lk
F = 500 N
500N x 1m
Ask: F = ___________ =
250 N
F =….?
2m
Reference:
how about other an aircraft??? is that used the same way??????
BalasHapusCan you tell me kind of aircraft in daily life ?
BalasHapusthanks..whether the magnitude of the lever to give effect to the force applied?
BalasHapuswhat kinds of aircraft? please tell me.
BalasHapusthanks ^^
