A motor runs at \(1500\ \text{rpm}\) and drives gear A having 20 teeth. Gear A meshes with gear B of 40 teeth, which is fixed on the same shaft as gear C having 15 teeth. Gear C meshes with gear D of 45 teeth that is fixed on a conveyor roller of radius \(0.20\ \text{m}\). Assuming ideal gears with no slip, determine (i) the angular speed of the conveyor roller in rpm and (ii) the linear speed of the belt in \(\text{m\,s}^{-1}\) (to two decimal places).

Answer Options

A. Angular speed = 125 rpm; linear speed ≈ 2.62 m/s
B. Angular speed = 300 rpm; linear speed ≈ 6.28 m/s
Correct Answer C. Angular speed = 250 rpm; linear speed ≈ 5.24 m/s
D. Angular speed = 500 rpm; linear speed ≈ 10.48 m/s
Correct Answer
C
Correct Option:
Angular speed = 250 rpm; linear speed ≈ 5.24 m/s
