ME6401 Important Questions KINEMATICS OF MACHINERY

ME6401 Important Questions KINEMATICS OF MACHINERY Regulation 2013 Anna University

Sample Me6401 important questions :

1. What is Kinematics?

Kinematics is the study of motion (position, velocity, acceleration). A major goal of
Understanding kinematics is to develop the ability to design a system that will satisfy Specified motion requirements. This will be the emphasis of this class.

2. What is Kinetics?

Kinetics is the study of effect of forces on moving bodies. Good kinematic design
should produce good kinetics.

3. Define Link.

A link is defined as a member or a combination of members of a mechanism
connecting other members and having relative motion between them. The link may consist of one or more resistant bodies. A link may be called as kinematic link or element. Eg: Reciprocating steam engine.

4. Define Kinematic Pair.

Kinematic pair is a joint of two links having relative motion between them. The types of kinematic pair are classified according to
Nature of contact (lower pair, higher pair)
To nature of mechanical contact (Closed pair, unclosed pair)
Nature of relative motion (Sliding pair, turning pair, rolling pair, screw pair,
spherical pair)

5. Define Kinematic Chain

When the kinematic pairs are coupled in such a way that the last link is joined to the first link to transmit definite motion it is called a kinematic chain.
Eg: The crank shaft of an engine forms a kinematic pair with the bearings which are fixed in a pair, the connecting rod with the crank forms a second kinematic pair, the piston with the connecting rod forms a third pair and the piston with the cylinder forms the fourth pair. The total combination of these links is a kinematic chain.

Eg: Lawn mower.

CE6405 important questions Soil Mechanics

CE6405 important questions Soil Mechanics Regulation 2013 Anna University.

Sample CE6405 important questions:

1. Define Soil mechanics.

Soil mechanics is defined as the application of the laws and principles of mechanics and hydraulics to engineering problems dealing with soil as an engineering material

2. What is compaction?

The process by which the porosity of a given form of sediment is decreased as a result of its mineral grains being squeezed together by the weight of overlying sediment or by mechanical means.

3. What is shrinkage limit?

The shrinkage limit (SL) is the water content where further loss of moisture will not result in any more volume reduction.

4. Define Liquid limit.

The plastic limit (PL) is the water content where soil starts to exhibit plastic behavior. A thread of soil is at its plastic limit when it is rolled to a diameter of 3 mm and crumbles. To improve consistency, a 3 mm diameter rod is often used to gauge the thickness of the thread when conducting the test.

5. What is Plasticity Index?

The plasticity index (PI) is a measure of the plasticity of a soil. The plasticity index is the size of the range of water contents where the soil exhibits plastic properties. The PI is the difference between the liquid limit and the plastic limit (PI = LL‐PL). Soils with a high
PI tend to be clay, those with a lower PI tend to be silt, and those with a PI of 0 tend to have little or no silt or clay

6. Define the term Liquidity Index.

The liquidity index (LI) is used for scaling the natural water content of a soil sample to the limits. It can be calculated as a ratio of difference between natural water content, plastic limit, and plasticity index: LI=(W‐PL)/(LL‐PL) where W is the natural water content.
