Introduction

When objects are accelerated, inertia-forces are generated. This is the case with rotating machine elements. The design of such parts must ensure that they perform their intended work under all the existing combinations of service loads and rotational forces or inertia forces. The rotation of a machine element results in an external vibrating force. The shaking force disturbs the supporting frame of the machine and the adjacent parts. It is also worth to note that the vibration generated by rotating machine elements and consequently the associated noise is also a serious problem to the machine operators. Therefore, it is very important ...

Introduction

Composites are mixtures of at least two materials, such as reinforcing elements, fillers, and composite matrix binder. Compared to concrete and timber, composites are relatively lightweight. Different composites differ in form and/or composition on a macroscopic scale. Each component retainsits identity and does not dissolve or merge completely into one another.
Composites are not generally used as fibres by themselves. They are often impregnated with a matrix material that transfers loads to the fibresand protects the fibres from abrasion and environmental attack. The useful properties of composites are diminished by the matrix to some extent but not fully.

Introduction

Newton's Second Law of motion asserts that the acceleration of an object exhibits a direct proportional relationship with the subsequent force acting on it. It explores the relationship that exists between force, mass and acceleration as exhibited by an object. This experiment examines Newton's Second Law of motion by enabling a dwindling weight to speed up a glider of recognised quantity along a track. A thread that links the dwindling mass to the glider is passed above a smart pulley (Knight, 2004). It is imperative to note that the smart pulley exhibits insignificant inertia, low friction and its revolution ...

Canada is witnessing a change in its work force – the percentage of workers aged above 45 has changed from 27% in 1993 to 40% in 2010; a phenomenon that is compelling the experts to re - examine the common beliefs about an aged work force. The Canadian demography is heading towards an increase in senior population with its baby boomers – those born between 1946 and 1965(Parkinson, McFarland & McKenna, 2015), reaching retirement age. Parkinson et al, (2015) predict serious implications on the Canadian economy, Government policies and the well being of Citizens unless significant adjustments are made to address ...

Calculations and Analysis

Analysis questions from lab: Part 1
Which side of the pan balance is lifted as you poured in the water? Was the solid cylinder forced up by the buoyant force of the water?

The left side; yes, slightly.

What happened to the left pan as you added water to the hollow cylinder? What can you say about the volume of the water you added to the hollow cylinder and the volume of the water (in the beaker) displaced by the solid cylinder? According to Archimedes' principle, should these volumes be the same?
As water was added to the hollow cylinder, the left ...

DEFLECTION OF BEAMSIntroduction

Any kind of modern day construction makes use of a component called structural beam, or beam. A beam helps in adding strength of any design or structure. Generally manufactured using steel, wood, or concrete, it is commonly used for spanning any open element of a structure. In any design work based on iron, steel I beam is the most commonly used one. On the other hand, home-based constructions generally make use of wooden beams. When steel I beam is encased within concrete, it forms a concrete beam and is typically used in the construction of heavy structures, such as ...
