Answer to Question #135533 in Mechanical Engineering for lloyd

Question

two points b and c lie on radial line of a rotating disk. the points are 2 inches apart. vb=700 ft/min and vc=880 ft/min. find the radius of rotation for each of these points. slader

Answer 1

Let the radius be r

let us assume C is at the edge

so distance from center

B will then be =

angular velocity will be same hence

Hence C is at 0.815 ft and B is at 0.648 ft
