Therefore, the amplitude of the pendulum’s oscillation is A =0.140 m = 14.0 cm. Example 2 Assume that the head of a jack-in-the-box toy is bouncing upward and downward on a spring. Furthermore, the angular frequency of the oscillation isω=π/6radians/s, and the phase shift isϕ...
The finite amplitude, free vibrational characteristics of a simple mechanical system consisting of an axisymmetric rigid body supported by a highly elastic tubular shear spring subjected to axial, rotational, and coupled shearing motions are studied. Two classes of elastic tube materials are considered:...

For more complex nonlinear systems, where the amplitude of excitation can vary in time or where time-dependent external disturbances appear, an analysis based on the frequency response curve may be insufficient. In this paper, a new tool to analyze nonli
Springs in parallel. What are the frequencies of vibration of a body of mass m = 5 k g (i) on a spring with modulus k 1 = 20 N / m ? (ii) On a spring with modulus k 2 = 45 N / m ? (iii) on the two springs in parallel?
On the basis of the analysis of the twisting vibration of rotary sucher-rod string, a formula of calculating every harmonic vibration eigenfrequency is presented. 在对旋转抽油杆柱的扭转振动分析的基础上 ,给出了各阶扭转振动固有特性参数的计算式 。 3. The paper introduces the main noise resource...
Answer to: Why, in terms of work and energy, did you have to push on the pendulum string as it was moving away from you in order to maintain a...
According to the fact that a universal coupling wasconstantly broken in a mine, the paper gave a common formula of the drive rate of a bi universal coupling on the basis of other people s work, and thus a universal conclusion was obtained that the drive rate can be kept constan ...
The geometry of the osteoblasts is selected as part of a sphere. The nucleus is modelled as ellipsoid because the nucleus is normally modelled as sphere [17] or ellipsoid [16,18,19]. In this study, the volumes of the cell and nucleus are ~3000 μm3and 104.5 μm3, respectively,...
doi:10.1023/A:1016307314234Nonlinear coupling dynamics between a spring-mass system and a finite amplitude sloshing system with liquid in a cylindrical tank is investigated. Based on a group of nonlinear coupling equations of six degrees of freedoms, analytical formulae of forces and moments of the...
