Shortly thereafter the virus was released. I wonder why? A depopulation secret meeting, perhaps. You say?]]>13Protection For AmericaTue, 07 Apr 2020 13:52:41 +0000

https://themathhelp.com/threads/angular-linear-speeds-3.3057/
https://themathhelp.com/threads/angular-linear-speeds-3.3057/invalid@example.com (puremath)puremathWe are given the rate of rotation of a wheel as well as its radius. In each case, determine the following:

A. the angular speed, in units of radians/sec;

B. the linear speed, in units of cm/sec, of a point on the circumference of the wheel;

C. the linear speed, in cm/sec, of a point halfway between the center of the wheel and the circumference.

https://themathhelp.com/threads/big-wheel-small-wheel.3060/invalid@example.com (puremath)puremathSuppose that a belt drives two wheels of radii r and R. (The picture cannot be uploaded. It is too large to be uploaded). The radius r of the small wheel is 6 cm and the radius R of the big wheel is 10 cm. The angular speed of the larger wheel is 100 rpm.

Determine the following:

A. The angular speed of the larger wheel in radians per minute.

I got 200(pi) rad/min

B. The linear speed of a point on the circumference of the larger wheel.

I got 2000(pi) cm/sec

C. The angular speed of...
