UNIT IV – BASICS OF SOLID MECHANICS

1 Write short notes on Stress. 4 K1

When a body is subjected to a system of external forces, it undergoes a deformation.

At the same time, by virtue of its strength, it offers a resistance against this

deformation. This internal resistance offered by the body to counteract the applied

load is called stress.

2

2 Define Strain. 4 K1

The deformation in unit original dimension is termed as ‘Strain’ and is denoted by

‘e’.

2

3 List out the types of stress and strains. 4 K2

1. Tensile Stress and Tensile Strain 2. Compressive Stress and Compressive

Strain 3. Shear Stress and Shear Strain

2

4 Define Shear Stress. 4 K1

When a body is subjected to two equal and opposite forces acting tangentially across

the resisting section, as a result of which the body tends to shear off across the

section, then this tangential force is termed as shear force and the stress induced is

called shear stress.

2

5 What do you meant by Elasticity? 4 K1

When an external force acts on a body, it undergoes some deformation. The property

by which a body returns to its original shape after the removal of external load is

elasticity.

2

6 State Hook’s Law. 4 K2

Hooke’s law states that when an elastic material is stressed within elastic limit, the

stress is proportional to the strain.

K = stress/strain

2

without any increase in the stress. Even for a small increase in stress the increase in

strain very large.

A beam made up of two or more different materials assumed to be rigidly connected

together and behaving like a single piece is known as composite beams.

2

12 What is meant by positive or sagging bending moment? 4 K1

The bending moment which causes a beam to bend with the concave side upwards, is

called a Sagging Bending Moment. This kind of bending moment is treated as a

positive bending moment.

2

13 When will be the bending moment is maximum? 4 K2

This is because if you try deriving both the bending moment and shear force

functions for any beam, the rate of change of the bending moment will give you the

shear force function, and there is zero rate of change when the bending moment is

at maximum or of constant value.

2

14 Define Method of Joints. 4 K1

The force in the member will be compressive if the member pushes the joint to

which it is connected whereas the force in the member will be tensile if the member

pulls the joint to which it is connected.

2

15 Where the Method of Section is used. 4 K1

When the forces in few members of a truss are to be determined, then the method of

section is mostly used. This method is very quick as it does not involve the solution

of other joints of the truss.

2

UNIT V – FLUID PROPERTIES

1 Define Fluid Mechanics. 5 K1

It is the branch of science, which deals with the behavior of the fluids (liquids or

gases) at rest as well as in motion.

2

2 Define Density of a Liquid. 5 K2

Density or mass density of a fluid is defined as the ratio of the mass of a

fluid to its volume. Thus mass per unit volume of a fluid is called density.

Density of fluid

Mass density (ρ) = fluid of Density /fluid of Mass

2

3 Define Specific Weight of a Liquid. 5 K2

Specific weight or weight density of a fluid is the ratio between the weight of a fluid

to its volume. The weight per unit volume of a fluid is called weight density.

Specific Weight = Weight of fluid/Volume of fluid

2

4 What do you meant by Specific Volume of a Liquid? 5 K2

Specific volume of a fluid is defined as the volume of a fluid occupied by a unit

mass or volume per unit mass of a fluid.

Specific Volume = Volume of fluid/ Mass of fluid

Thus specific volume is the reciprocal of mass density. It is expressed as m3/kg. It is

commonly applied

2

5 Define Specific Gravity of a Liquid. 5 K1

Specific gravity is defined as the ratio of the weight density of a fluid to the weight

density of a standard fluid.

8 Define Kinematic Viscosity. 5 K1

ʋ = µ/ρ

Unit : m2/sec

2

9 Define Compressibility. 5 K1

Compressibility is the reciprocal of the bulk modulus of elasticity, K which is

defined as the ratio of compressive stress to volumetric strain.

2

10 Distinct between capillarity and surface tension. 5 K1

Capillarity is defined as a phenomenon of rise or fall of a liquid surface in a small

tube relative to the adjacent general level of liquid when the tube is held vertically in

the liquid. The rise of liquid surface is known as capillary rise while the fall of the

liquid surface is known as capillary depression.

Surface tension is defined as the tensile force acting on the surface of a liquid in

contact with a gas or on the surface between two immiscible liquids such that the

contact surface behaves like a membrane under tension

2

11 Define Temperature of a liquid. 5 K1

In general, the liquids tend to expand when their temperature increases. For example,

the same mass of boiling water occupies more volume at 100 degrees Celsius than at

20 degrees Celsius. Therefore, increasing temperature decreases density - Decrease

viscosity and decrease density and Decrease viscosity and increase density

2

12 What is meant by vapour pressure of a liquid? 5 K2

Vapor pressure or equilibrium vapor pressure is defined as the pressure exerted by

a vapor in equilibrium with its condensed phases (solid or liquid) at a given

temperature in a closed system. The equilibrium vapor pressure is an indication of a

liquid's evaporation rate. It relates to the tendency of particles to escape from the

liquid (or a solid).

2

13 What do you meant by Capillary tension? 5 K1

Capillary action (sometimes capillarity, capillary motion, or wicking) is the ability of

a liquid to flow in narrow spaces without the assistance of, or even in opposition to,

external forces like gravity. If the diameter of the tube is sufficiently small, then the

combination of surface tension (which is caused by cohesion within the liquid)

and adhesive forces between the liquid and container wall act to propel the liquid.

2

14 Write down the expression for Capillary Fall. 5 K2

Height of depression in tube h = 4σCosθ/ ρ X ɡ X d 2

15 Two horizontal plates are placed 1.25cm apart. The space between them being filled

with oil of viscosity is 14 poises. Calculate the shear stress in oil if upper plate is moved

with a velocity of 2.5 m/s

5 K3

Solution:

Given:

Distance between the plates dy = 1.25 cm = 0.0125 m

Viscosity µ = 14 poise = 14/10 Ns/m2

Velocity of upper plate u = 2.5 m/s

Shear stress is given by equation as τ = µ du/dy

Where du = the change of velocity between the plates = u-0 = u = 2.5 m/s

dy = 0.0125 m

τ = (14/10) x (2.5/ 0.0125) = 280 N/m2

1 The diameter of a small piston and a large piston of a hydraulic jack at 3 cm

and 10 cm respectively. A force of 80 N is applied on the small piston. Find the

load lifted by the large piston when:

a) The pistons are at the same level

b) Small piston in 40cm above the large piston

The density of a liquid in the jack is given as 1000kg/m3

2 A vertical gap 2.2cm wide of infinite extent contains a fluid of viscosity 2.0

Ns/m2 and specific gravity 0.9. A metallic plate 1.2 m x 1.2m x 0.2 cm is to be

lifted up with a constant velocity of 0.15 m/sec, through the gap. If the plate is

in the middle of the gap,find the force required. The weight of the plate is 40 N.
