1.
Determine the elongation in a helical steel spring composed of 20 turns of 20 mm-diamter wire on a mean radius of 80 mm when tha spring is supporting a load of 2 kN. Use G = 83 GPa

2.
It is the point at which there is an appreciable elongation of the material without any corresponding increase of load.

3.
It is the measure of the total resistance to sliding

4.
It occurs when a member carries a load perpendicular to its long axis while being supported in a stable manner

5.
The proportional limit is the value of stress on the stress-strain diagram curve at which the curve first deviates from a straight line.

6.
This implies the resistance to shock or difficulty of breaking and express the work per unit volume required to fracture a materia

7.
A solid steel shaft 5 m long is stressed to 80 MPa when twisted through 4 degrees. Using G = 83 GPa, compute the shaft diameter.

8.
It is the ability of a material to absorbed applied energy without failure

9.
The reciprocal of bulk modulus of any fluid is called

10.
A steel rod having a cross-sectional area of 300 sq. Meters and a length of 150 m is suspended vertically from one end. It supports a tensile load of 20 kN at the lower end. If the unit mass of steel is 7850 kg/m^3 and E = 200×10^3 MN/m^2, find the total elongation of the rod

11.
Kinematic viscosity in SI derived unit is described as:

12.
Find the elongation in a 3m long steel bar by subjecting it to 50 Mpa stress. E=200 Gpa

13.
These are components of the total resistance to sliding the portion to one side of the exploratory section past the other

14.
It is a measure of the stiffness of a material determined by the slope of the straight-line portion of the stress-strain curve

15.
It is the ability of a material to be elongated

16.
Galvanized iron is a term referring to iron coated with:

17.
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

18.
It is the measure of the resistance to twisting.

19.
It occurs when a cutting action is applied as you would see with scissors, tin snips, or punches

20.
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
