![]() Department of Vehicle Engineering, School of Rail Transportation, Soochow University, Suzhou 215131, Jiangsu, China. Now study the lateral displacement of the string from the initial position. Nonlinear transverse vibration of nano-strings based on the differential type of nonlocal theory. If there is an initial stretching of L, the initial tension T must be T ES L L by Hooke’s law, where E is Young’s modulus. The speed of a wave in a flexible stretched. Referring to Figure 1, consider a taut string stretched between two xed points at x 0 and x L. Speed of waves in a stretched string: A string means a wire or a fiber which has a uniform diameter and is perfectly flexible. Theory of the Wave Equation Suppose a string with a linear mass density (mass per unit length) of ρ is fixed at both ends and is placed under a tension T. Since we are concerned with transverse vibrations on the string, the relevant restoring force (per unit length) is given by the string tension times the. Electrically maintained tuning fork, fine thread, scale pan, weights and meter scale. In this experiment, the relationship between the tension in a string and the vibrational frequencies of a standing wave pattern will be examined. Standing waves (for both longitudinal and transverse wave motion) are extremely important since many bodies vibrate with standing waves. To understand these vibrations, you have to understand a classical type of wave called a standing wave a wave that doesn’t appear to be moving. The characteristics of transverse waves can be studied using standing waves on a stretched string. String theory depicts strings of energy that vibrate, but the strings are so tiny that you never perceive the vibrations directly, only their consequences. Examples of transverse waves include vibrations on a. sound, where the medium and the wave move along the same direction but we will focus on the transverse case.). ![]() In transverse wave motion, the displacement of the particles is perpendicular to the direction of the wave propagation. String waves are an example of transverse waves because the string moves up and down at right angles to the horizontal motion of the wave. ![]() For longitudinal waves, the displacement of each particle of the medium is parallel to the direction in which the wave propagates. Waves on a String introduction Wave motion is the underlying principle for many common phenomena (sound, musical instruments, light, X-rays, etc.) and may be transverse or longitudinal in nature. ![]()
