A circular disc having a mass of \(30 \mathrm{~kg}\) is moved asymmetrically between two bearings \(A\) and \(B\) as shown in the Fig.56. It is used as an eccentric cam with an eccentricity of \(0.01 \mathrm{~m}\). If the shaking force on each of the bearings is not to exceed \(1500 \mathrm{~N}\), the speed of rotation of the cam should not exceed

(a) \(10 \mathrm{rad} / \mathrm{s}\)

(b) \(100 \mathrm{rad} / \mathrm{s}\)

(c) \(70.7 \mathrm{rad} / \mathrm{s}\)

(d) \(140 \mathrm{rad} / \mathrm{s}\)
