material is exceeded. The material is said to be under the property of
_______________.
3- There are three kinds of stress
and strain: _______________, ______________, and _______________.
4- When equal and opposite forces
are exerted on a body along the same line of action. The body is said to be
under _______________.
5- The ability to withstand plastic
deformation before fracturing this property is called _______________.
Q.III/ Give one word for each of the underlined words. Make
any small changes you think necessary:
1- Tension makes a material longer.
2- A chromium-steel ball has the ability to resist
scratching by other materials.
3- When a material is subjected to forces which are
coming from outside, it is deformed.
4- When equal forces directed away from each otheract on a body, they elongate it.
5- We can easily cut a mark on some metals with
something pointed.
Q.IV/ Translate the following
paragraph into Arabic: (5 m)
The
property of elasticity is used to increase our comfort safety. The various
springs in cars, trains and pieces of furniture and the tyres on automobiles
are just a few examples where this property of elasticity is of great
importance.
Foundations are compressed
by the loads. They are in compression. Gases are easily compressed. They are
compressible.

Q.IV/ Translate the following
paragraph into Arabic: (5 m)
Not
only does friction slow down machines but it is destructive and wasteful. It
produces heat where it is not wanted and causes wear of moving parts. In order
to cut down friction losses to the minimum engineers use ball bearings or
roller bearings because rolling objects cause less friction than sliding ones.
Moreover, ball bearings or roller bearings keep the shaft centered and are easy
to lubricate.

5-
What is relation between stress and strain?
Q.IV/ Translate the following paragraph into Arabic: (5 m)
If a
metal is subjected to a constant stress for a long period while it is kept at a
relatively high temperature, a kind of deformation called high temperature
creep will happen in the metal. High temperature must be considered in devices
such as boilers and turbines, where metals are stressed at relatively high
temperatures. In some materials such as lead and glass, creep deformation
occurs even at normal temperatures.

Q.IV/
Translate the following paragraph into Arabic: (5 m)
Although friction is always considered a wasteful force,
there are many useful applications for the force of friction. It would be
impossible for a person to walk or run on a completely frictionless surface.
Nails and screws remain in their holes because of frictional forces. Friction is essential when
energy is transferred from a motor to a
machine by means of a belt. Again, friction between the tyres and the road is
needed to move, slow down or stop a car.
