ABSRTACT

A mechanism is a simplified model, usually in the form of a line diagram, which is used to reproduce exactly the motion occurring in machine. Some machine used in industry applied the crank and slotted lever quick return mechanism in the machine operation. So in this experiment we are to investigate the performance of this quick return mechanism. The apparatus used for this experiment also called crank and slotted lever quick return mechanism equipment by Norwood Instrument Ltd. The various parts of this mechanism are called links or elements. The quick return is caused by the variation of length of the links itself. This experiment is carried out by rotating the crank for a revolution (360°). Then the slider position value is read and recorded for each 10° increment. Finally the theoretical slider position value and slider velocity value and could be calculated for analyzing purpose.

OBJECTIVE

The objective of this experiment is to investigate the kinematics motion of a Crank and Slotted Lever Quick Return mechanism. The investigation is to show that it is indeed a quick return mechanism and to evaluate the increase in efficiency that this would offer if applied to a machine tool.

...Teaching trigonometry using Empirical Modelling

Abstract
The trigonometric functions sin(x), cos(x) and tan(x) are relationships that exist between the angles
and length of sides in a right-angled triangle. In Empirical Modelling terms, the angles in a triangle
and the length of the sides are observables, and the functions that connect them are the definitions.
These well-defined geometric relationships can be useful when teaching GCSE-level students about
the...

...Right Triangle TrigonometryTrigonometry is a branch of mathematics involving the study of triangles, and has applications in fields such as engineering, surveying, navigation, optics, and electronics. Also the ability to use and manipulate trigonometric functions is necessary in other branches of mathematics, including calculus, vectors and complex numbers. Right-angled Triangles In a right-angled triangle the three sides are given special names. The side...

...Trigonometry (from Greek trigōnon "triangle" + metron "measure"[1]) is a branch of mathematics that studies triangles and the relationships between the lengths of their sides and the angles between those sides. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves. The field evolved during the third century BC as a branch of geometry used extensively for astronomical...

...Trigonometry
| Introduction to trigonometryAs you see, the word itself refers to three angles - a reference to triangles. Trigonometry is primarily a branch of mathematics that deals with triangles, mostly right triangles. In particular the ratios and relationships between the triangle's sides and angles. It has two main ways of being used: 1. In geometryIn its geometry application, it is mainly used to solve triangles, usually right triangles. That is,...

...EXPERIMENT 4.1 – SCOTCH YOKE MECHANISM
BACKGROUND OF STUDY:
Pure simple harmonic motion is produced by the Scotch Yoke mechanism when driven by an eccentric or crank.
Its early application was on steam pumps but it is not suitable for high speeds due to the backlash in the scotch yoke. It is now mainly used in computing type applications where harmonic motion is required.
The Scotch yoke is a mechanism for converting the linear motion of a...
