Simple harmonic motion

Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards…

Simple Pendulum

A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.

Oscillation

In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion tak…

Textbook Question

Chapter 18, Problem 18.74AP

Review. The top end of a yo-yo string is held stationary. The yo-yo itself is much more massive than the string. It starts from rest and moves down with constant acceleration 0.800 m/s² as it unwinds from the string. The rubbing of the string against the edge of the yo-yo excites transverse standing-wave vibrations in the string. Both ends of the string are nodes even as the length of the string increases. Consider the instant 1.20 s after the motion begins from rest. (a) Show that the rate of change with time of the wavelength of the fundamental mode of oscillation is 1.92 m/s. (b) What if? Is the rate of change of the wavelength of the second harmonic also 1.92 m/s at this moment? Explain your answer. (c) What if? The experiment is repeated after more mass has been added to the yo-yo body. The mass distribution is kept the same so that the yo-yo still moves with downward acceleration 0.800 m/s². At the 1.20-s point in this case, is the rate of change of the fundamental wavelength of the string vibration still equal to 1.92 m/s? Explain. (d) Is the rate of change of the second harmonic wavelength the same as in part (b)? Explain.

The elastic limit of a steel wire is 2.70 × 108 Pa. What is the maximum speed at which transverse wave pulses can propagate along this wire without exceeding this stress? (The density of steel is 7.86 × 103 kg/m3.)

A guitar string of length L = 0.71 m is oriented along the x-direction and under a tension of T = 92 N. The string is made of steel which has a density of ρ = 7800 kg / m3. The radius of the string is r = 8.9 x 10-4 m.A transverse wave of amplitude A = 0.0020 m is formed on the string. Calculate the mass per unit length μ of the guitar string in kg/m.

A musical note on a piano has a frequency of 40 Hz. If the tension in the 2-m string is 308 N, and one-half wavelength occupies the string, what is the mass of the wire? 0.024 kg 0.047 kg 0.031 kg 0.019 kg 0.040 kg A block attached to a spring, oscillates on a frictionless horizontal surface with a period of 0.3 s. The time needed by the block to move (for the first time) from position x = -A to x = -A/2 is: 0.3 sec 0.05 sec 0.2 sec 0.15 sec 0.1 sec The equation of motion of a particle in simple harmonic motion is given by: x(t) = 0.2cos(ωt), where x is in meters and t is in seconds. At x = 0, the particle’s velocity is v = -1.256 m/s. The period of oscillation, T, equals: 1.5 sec 0.25 sec 1 sec 3 sec 0.5 sec In an oscillatory motion of a simple pendulum, the ratio of the maximum angular acceleration, θ''max, to the maximum angular velocity, θ'max, is π s^(-1). What is the time needed for the pendulum to complete two oscillations? 0.5 sec 1 sec 4 sec 0.25 sec 2…
