Chapter 11, Problem 37A
Why does a washing machine vibrate violently if the clothes are not evenly distributed in the tub?
Expert Solution & Answer
To determine
To explain: The reason for the violent vibrations in washing machine if the clothes are not evenly distributed in the tub.
Answer to Problem 37A
Due to disturbance in center axis clothes starts turbulence and machine starts vibrating.
Explanation of Solution
Introduction:
Disturbing the spinning axis creates an uneven revolution of objects around. This creates wobbling.
When the Center of Gravity is not along the spin axis, wobbling will occur. This creates turbulence in the tub. That is why, when clothes are not distributed evenly in the tub, their spinning axis gets disturbed and the washing machine vibrates violently.
Conclusion:
Due to disturbance in the spinning axis, turbulence occurs and the uneven distribution of clothes creates wobbling in the machine and it starts vibrating.

Set the wavelength to the (default) 0.55 microns and a single on-axis field point at infinite object distance. Set the image distance to 200 mm. Make the first surface the stop insure that the lens is fully filled (that is, that the entrance beam has a radius of 10 mm). Use the lens-maker's equation to calculate initial glass curvatures assuming you want a symmetric, bi-convex lens with an effective focal length of 200 mm. Get this working and examine the RMS spot size using the "Text" tab of the Spot Diagram analysis tab (OpticStudio) or the Spd command of the text widnow (OSLO). You should find the lens is far from diffraction limited, with a spot size of more than 100 microns. Now let's optimize this lens. In OpticStudio, create a default merit function optimizing on spot size.Then insert one extra line at the top of the merit function. Assign the…arrow_forward
