Sagot :
The largest ratio of the circular disk at the two points is ac2/ac1.
The given parameters:
- Location of point 1 = r1
- Location of point 2 = r2 = 2r1
What is angular speed?
- The angular speed of an object is the rate of change of angular displacement of the object.
The angular speed of each disk is given as;
[tex]\omega = 2\pi N[/tex]
where;
- N is the number of revolutions
thus, the angular speed is independent of radius of the circular disk
ω2/ω1 = 1
the centripetal acceleration of each disk is calculated as follows;
[tex]a_c = \frac{v^2}{r} \\\\a_c_1 = \frac{v^2}{r_1} \\\\a_c_2 = \frac{v^2}{2r_1} \\\\\frac{a_c_2}{a_c_1} = \frac{2r_1}{v^2} \times \frac{v^2}{r_1} = 2[/tex]
the angular acceleration of the disk is calculated as follows;
[tex]\alpha = \frac{\omega }{t}[/tex]
the angular acceleration is independent of the radius of the disk.
α2/α1 = 1
Thus, the largest ratio of the circular disk at the two points is ac2/ac1.
