Viscosity measurement

Viscosity is an important property of a fluid and by this property fluid’s resistance of flow is measured. In other words, viscosity is a quantification of resistance of fluid to gradual deformation by shear stress. So, by this property shear stress in a fluid and angular rate of deformation are correlated. The resistance in a fluid is offered by intermolecular friction applied while layers of fluid slide by one another. Highly viscous fluid resist its flow and low viscous fluid like gas flows easily.

Objective:

Purpose of this lab experiment was to quantity viscosity, shear stress, strain Continue reading...

Introduction

A motorcycle suspension system helps in dual manner – support the vehicle brake and maintain the balance. This directly translates in to the bike’s safety and provides suitable comfort and balance to the rider. The function of the suspension system is to absorb the shocks while handling, breaking or while simply riding on the road. The vibrations caused while running the vehicle are ‘dampened’. Thus, the name ‘vibrations damper’ for the shock absorbers. The rear suspension, also called “rising-rate” is popularly used in motorcycle design and manufacturing. Here the wheel is suspended by Continue reading...

Experiment 1 (Drilling Fluid Mud Density)

Definition: The drilling fluid term refers to the technic used for facilitation of drilling boreholes, and to improve all necessary functions needed for a fine drilling.

Results:

Results:
(The weight of Mud *0.052)= Gradient of Mud in psi/ft.
(The weight of Mud in lb/ft3)/144=mud gradient in psi/ft.

Water:

(Mud gradient) 8.3*0.052 =0.432 psi/ft.
(Mud gradient) 64/144 =0.044 psi/ft.

Mud sample No1:

(Mud gradient) 9.13*0.052=0.475 psi/ft.
(Mud gradient) 69/144=0.480 psi/ft.

Mud sample 2:

(Mud gradient) 10*.052=0.520 psi/ft.
(Mud gradient) 76/144=0.530 psi/ft.

Calculation: For calculation of the Density and Mud gradient, the following formulas were used.

Density= (lb/gal)/ 8.345.
Mud gradient= (lb/gal)/ 19.24.

Volume and mass

Density:
Fresh Water: 8.3/8.345 = 1.0 (S.G)
Mud sample1: 9.13/8.345=1.1 (S.G)
Mud sample 2: 10/8.345=1.20 ( Continue reading...

ABSTRACT

Continuum mechanics is a combination of physical laws and mathematics that estimate the behavior of matter that is prone to mechanical loading. The basic equations involved in continuum mechanics may be formed in two distinct but fundamentally parallel formulations. In continuum mechanics, deformation is the transformation of certain bodies or objects from a reference shape to a present shape. This paper explores the different types of deformation in continuum mechanics.

Keyword: continuum mechanics, deformation, stretch, rotation, strain, physics laws, mathematics

INTRODUCTION
The examination of the mechanical and kinematic characteristic of materials demonstrated on the continuum postulation is termed as continuum mechanics. Continuum mechanics is divided into two Continue reading...

Question 1: (Metallic Materials)

Recrystallization:
This is the process of growth of grain fragments in an alloy when it’s being worked on. This affects materials properties and services while in use.
Examples such as steel’s properties are affected such that there is reduction in strength and hardness of the material and this affects its applications and behavior in service. Other materials such as copper are affected in the same way.

Hot or cold working:

Hot or cold working involves hardening of materials and also and also heating the material. Iron is an example and is affected by hot working where it can be cast in Continue reading...

Mass wasting is defined as the downward movement of loose rock, soil, mud and regolith under the force of gravity. The nature of flow is determined by the cohesive and frictional forces between the particles and agents like water play an important role in transporting the material to lower elevations. This article focuses on Creep, Earthflow, Mudflow, Rock falls, Rockslides and Underwater landslides.
Creep- Creep or Soil Creep is a very slow and long term process of downslope movement of soil. Shear forces, over time, are only slightly greater than shear strengths. Creep is triggered by gravity and the Continue reading...

In chemistry, at a room temperature a different structure varieties of methylmethacrylate monomer permits to produce solid PMMA with help of polymerization. Reaction is usually fastened by the cupidity of the polymer, which is dissolved in polymer (Webb and Spencer, 2007). The dynamic viscosity (η) of substances is usually calculated by diving stress (F) by rate (S) (η = F/S). When we have viscosity decrease and shear rate increase – cement in liquid state is formed. This process has shear thinning performance and has a definition of “pseudo plastic” (Webb and Spencer, 2007). As we know, while polymer chains grow in length, the Continue reading...

In the Journal of Advanced Materials submission by (Flambard and Polo, 2002) on the stab resistance of the multi-layers, an in-depth comparison was made between the Para-aramid and PBO fibres. The comparison based on the performance of the PPT and the PBO fibres. The experiment was conducted extensively on the stab resistance bench, and the results were recorded at each and every step and then analysed. The solution that was arrived on about the various pointed edges of the test weapons that were used in the experiment were all meant to simulate the effect of the extent of such Continue reading...
