1.
The reciprocal of bulk modulus of any fluid is called

2.
It is the internal resistance offered by a unit area of the material from which a member from which a member is made to an externally applied load

3.
It is the highest value of apparent stress on the stress-strain curve.

4.
Internal force that acts against distortion

5.
A ductile material is one that can be stretched, formed, or drawn to a significant degree before fracture. A metal that exhibits a percent elongation greater than ____ % is considered to be ductile

6.
It is a measure of the resistance that a body’s mass and distribution of its mass about the axis of rotation. This property is known as

7.
Galvanized iron is a term referring to iron coated with:

8.
This implies the resistance to shock or difficulty of breaking and express the work per unit volume required to fracture a materia

9.
A solid steel shaft is not to twist through more than 3 degrees in a 6 m length when subjected to a torque of 12 kN.m. What maximum shearing stress is developed? Use G=83GPa

10.
A steel rod 2.5 m long is secured between two walls. If the load on the rod is zero at 20 degree Celsius, compute the stress when the temperature drops to -20 degrees Celsius. The cross-sectional are if the rod is 1200 sq. mm, coefficient of linear expansion = 11.7 um/(m-deg.C), and E = 200 GPa. Assume that the walls are rigid.

11.
A brittle material is one that fails suddenly under load with little or no plastic deformation. A metal that exhibits a percent elongation ____ 5.0% is considered to be brittle

12.
Ivory soap floats in water because

13.
It occurs when a cutting action is applied as you would see with scissors, tin snips, or punches

14.
A cylinder pressure vessel is fabricated from plates which have a thickness of 20mm. The diameter of the pressure vessel is 450 mm and its length is 3.5m. Determine the maximum internal pressure which can be applied if the stress in the steel is limited to 150MPa.

15.
The specific gravity of the substance is the ratio of the density of the substance to the density of water. Another term for specific gravity is:

16.
It is the value of stress on the stress-strain curve at which the material has deformed plastically; that is, it will no longer return to its original size and shape after removing the load

17.
What is the theoretical maximum value of Poisson’s ratio of any given material subjected to a uniform triaxial stress

18.
It occurs when a member carries a load perpendicular to its long axis while being supported in a stable manner

19.
What is the minimum diameter of a solid steel shaft that will not twist through more than 3 degrees in a 6 m length when subjected to a torque of 12 kN.m? Use G=83GPa.

20.
The property by virtue of which a body tends to return to its original size or shape after a deformation and when the deforming forces have been removed
