2. Figure Q2 (c) shows a belt drive used to transmit power from electric motor A to a fan. The electric motor A is rotated at 4000 RPM. The diameter of electric motor pulley A and fan's pulley B is 50 mm and 180 mm respectively. Fan - 180 0,- 50 MM Figure Q2 (c) (a) Find the velocity ratio of both pulleys A and B. (b) Calculate the operating speed of the fan. (c) Determine the belt speed. (d) Find the angular acceleration of both pulleys A and B if the tangential acceleration of the belt is 0.8 m/s2.
