1.
It is the ability of a material to absorbed applied energy without failure
2.
A steel bar 50 mm in diameter and 2 m long is surrounded by a shell of cast iron 5 mm thick. Compute the load that will compress the combined bar a total of 0.8 mm in the length of 2m. For steel E = 200 GPa, and for cast iron E = 100 GPa
3.
It is the highest value of apparent stress on the stress-strain curve.
4.
It is the indication of the resistance of a material to indentation by a penetrator
5.
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
6.
A leak from a faucet comes out in separate drops. Which of the following is the main cause of this phenomenon
7.
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
8.
It is the maximum safe stress that a material can carry
9.
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
10.
It is a measure of the stiffness of a material determined by the slope of the straight-line portion of the stress-strain curve
11.
It is the measure of the resistance to twisting.
12.
Ivory soap floats in water because
13.
It occurs when a member carries a load perpendicular to its long axis while being supported in a stable manner
14.
It is the value of stress on the stress-strain curve at which there is a significant increase in strain with little or no increase in stress
15.
Internal force that acts against distortion
16.
This implies the resistance to shock or difficulty of breaking and express the work per unit volume required to fracture a materia
17.
This component measures the pulling (or pushing) action perpendicular to the section
18.
These are components of the total resistance to sliding the portion to one side of the exploratory section past the other
19.
It is the measure of the total resistance to sliding
20.
The proportional limit is the value of stress on the stress-strain diagram curve at which the curve first deviates from a straight line.
