To calculate: The amplitude of the oscillations of the weight.
Answer to Problem 129RE
The required amplitude is
Explanation of Solution
Given information:
The model:
Calculation:
Given the equation of displacement of the harmonic system is:
To find the amplitude of the equation (1), change the equation to the form of
Multiply and divide the right hand side of the equation (1) by the square root of the sum of the squares of the amplitude of the trigonometric part that is,
Here, the amplitude of the sine function is 1.
So, substitute 1 for
Hence, the required amplitude is
