(a)
To find: What is the minimum height of the tip of the labeled fan blade above the ground.
The minimum height of the tip of the labeled fan blade above the ground is 30 inches.
Given information:
Given that the length of the blade is
Calculation:
The diameter of the fan is 18 inches and the maximum height is 48 inches.
The minimum height of the tip of the labeled fan blade above the ground is:
(b )
To find: What is the model for the height and time .
The model for the height and time is
Given information:
Given that the length of the blade is
Calculation:
In order to find the model for the height and time it is required to find the amplitude, period, phase shift, vertical shift.
The general sinusoidal model is:
800 revolution is done in
The maximum height of blade from the ground is 48 inches.
Period of the blade will be calculated as:
Now in order to find
The midline of the handle will be:
Here
Find amplitude with formula
Substitute all the values in the general equation of model gives:
(b )
To find: Do the answer will change if the fan rotates clockwise. Why?
The model will change by the sign if the rotation is clockwise.
Given information:
Given that the length of the blade is
Calculation:
If the motion is clockwise the model will change by the sign because the angle will change by
