1.
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.
2.
It is a measure of pulling and pushing force
3.
It is the ability of a material to be elongated
4.
It is the point at which there is an appreciable elongation of the material without any corresponding increase of load.
5.
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
6.
This implies the resistance to shock or difficulty of breaking and express the work per unit volume required to fracture a materia
7.
It is the measure of the total resistance to sliding
8.
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
9.
It is the maximum safe stress that a material can carry
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.
The property by virtue of which a body tends to return to its original size and shape after a deformation and when the deforming forces have been removed.
12.
It occurs when a member carries a load perpendicular to its long axis while being supported in a stable manner
13.
A leak from a faucet comes out in separate drops. Which of the following is the main cause of this phenomenon
14.
It describes the luminous flux incidence per unit area and is expressed in lumens per square meter.
15.
It is the highest value of apparent stress on the stress-strain curve.
16.
This component measures the pulling (or pushing) action perpendicular to the section
17.
Galvanized iron is a term referring to iron coated with:
18.
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
19.
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.
20.
Kinematic viscosity in SI derived unit is described as:
