In front of the antique sewing machine museum in arlington, texas, the largest sewing machine in the world, the flywheel, which turns as the machine sews, is 5 feet long in diameter.
Amplitude = 2.5 ft
-------------------------------
Write a model for the height, h (in feet), of the handle on the flywheel as a function of the time, t (in seconds), assuming that the wheel makes a complete revolution every 2 seconds
----
Period = (2pi)/b = 2
b = pi
==========
and that the handle starts at its minimum height of 4 feet above the ground.
Vertical shift of 6.5 ft.
Horizontal shift of -pi/2
=============================
Equation: y = 2.5sin(pi(x)-(pi/2)) + 6.5
----------------------------------------
