...Mechanics Introduction Earth is extremely rich in soil and minerals and the terrain we find is of different types and kinds. Soil is made up of three components: solid particles, air, and water. The particles are classified by size as clay, silt, sand, gravel, cobbles, or boulders. The amount of air and water within a sample of soil affects its behavior. The sizes and types of particles that constitute a particular soil affect its properties and thus its load-carrying ability and compressibility. However the soil we find is hardly perfect for any kind of construction before any steps are taken to harden the soil. This is usually because soil is by natural forces in tension...

OBJECTIVE: TO STUDY THE MOMENT OF INERTIA OF A FLYWHEEL BY ACCELERATING IT USING A FALLING MASS
Theory
The flywheel is made of a heavy circular disc that is fitted to an axle that projects on either side. The axle is mounted on two fixed supports on ball bearings. The axle has a small peg that is attached to a cord. The other carries the weight (Amrita.vlab.co.in, 2014).

...Mechanics— Verification of Bernoulli’s Equation The behavior of the laminar fluid motion along a converging-diverging tube of known cross-sectional area, at different flow rates, is investigated, and the mass as well as energy conservation laws are verified in this experiment. Another objective of performing it is to measure the loss of energy due to viscous resistance to the fluid the motion in case of higher flow rates. The results obtained from the experiment not only verify the basic laws and characteristics of a fluid in motion, but also determines the losses incurred in energy due to resistive forces.

...Mechanics—Bernoulli’s Equation Using the conservation laws of streamline motion of fluid, we investigate the behavior of the fluid motion along a converging-diverging tube of known cross-sectional area, at different flow rates. The energy lost as a result of viscous resistance of the fluid the motion when the flow rate increases, may also be measured as Head Lost.
Introduction
When an incompressible fluid starts moving along streamlines, two basic laws get satisfied. One can use these two laws to check the behaviour of the dynamics of the fluid. Moreover, both these laws pertain to certain conservation of fluid properties—

Head Loss Fluid Mechanics

...Mechanics Introduction Fluid flowing in pipes is usually turbulent. The flow is considered turbulent if the Reynolds value is greater than 4000. During the turbulent flow, the velocity distribution is relatively the same (or uniform) and the velocity profile is flatter in comparison to the laminar flow. It is important to note that there are pressure fluctuations and irregular velocity in turbulent flow. In turbulent flow, fluctuations in velocity influence the mean motion such that it causes additional shear resistance to the flow. The turbulent shear stress is composed of shear stress and viscous shear stress generated because of turbulence (Sawhney 2011, p629). Fluid flowing... ?Head Loss Fluid...

The general theory applies to all liquids but since there are a few test data available on open-channel flow of liquids other than water at natural temperatures, it only applies to water.

...Mechanics (a) Describe with the use of suitable diagrams the critical strength of soil. Critical is a condition that occurs in the soil where shear distortions develop without effective stress, void ratio and deviatoric stress changes (Schofield 1998). As such, soil and associated granular materials attain a critical state after they get a continuous distorted, which makes them assume frictional fluid flow (see figure 1). As such, the maximum shear stress, which the soil can bear, gives the shear strength of the soil. Excess shear stress results in the failure of the soil, which may occur mostly because of catastrophic loading on the material (see figure 2). The soil attains a critical state...

...Mechanics 230 INTRODUCTION Drag could be identified as a resultant forces causing resistance to motion in bodies moving within fluids (Tipler 2004). Unlike other frictional forces experienced in moving objects, drag forces normally remain fully dependent on velocity of objects. These forces have been identified as reducing velocity of objects moving within fluids depending on the size of objects. Various types of drag exist when studying drag resulting from movement of physical bodies within fluids. The different types of drags are as discussed below. TYPES OF DRAG Form drag This could be described as the frictional force resulting from the shape of a moving object. This drag remains highly... ?Fluid...
