Abstract:

This paper deals with the first and higher-order function-generation problems in the synthesis of linkages with relatively small input cranks. Such linkages tend to produce nearly simple harmonic motions at the output members. Owing to this distinction, the generality of the conventional synthesis techniques is no longer applicable. Thus, in function generation, only harmonic functions of the input motion may be expected to be synthesized for output motions.

AbstractIn this study, we have considered the elliptical harmonic motion which is the superposition of two simple harmonic motions in perpendicular directions with the same angular frequency and phase difference of π/2 . It is commonly recognized that a convenient formulation for problems in planar kinematics is obtained by using number systems. Here the elliptical numbers are used to derive the Bobillier formula with two different methods for aforesaid motion; the first method depends on the Euler-Savary formula and the second one uses the usual relations of the velocities and accelerations.

Abstract:

The interference pattern between two harmonic oscillations with slightly different frequencies are called beats. The beats, as a combined motion, have two different periods, one approximately equal to the period of the original oscillations, and another that is significantly longer and is related to the variable amplitude of the motion. The main objective of this presented work is to engage students’ attention and demonstrate in a simple way the concept of mechanical beats as a resultant motion of combined oscillations, but also to experience it through a visual projection. The proposed experi

Abstract:

A simple harmonic theory is proposed to describe the regulatory mechanism of tropomyosin in the activation of muscle contraction. The theory proposes that activation-associated displacement of tropomyosin is inherent to tropomyosin, a consequence of the molecule's large-scale vibrational motion (5-10 A root mean square displacement). In association with thin filament the vibrational motion may become less complex, approaching the ideal case of simple harmonic motion. The degree of activation increases as the amplitude of the simple harmonic motion increases, causing tropomyosin to shorten leng

Abstract:

It aims to explain the motion law of simple harmonic vibration in phase space with the complex part of differential equation. Introduce and enumerate differential equations, classify and discuss each case, and finally get the appropriate formula. Angular velocity, phase, displacement, time, amplitude, acceleration and trigonometric function are connected by equation solution. It explains the rationality of physics in phase space, and does not restrict the limited operation with real space. Using the knowledge of second order differential equation, the formula of angular velocity of simple harm
