A circular rim 28 inches in a diameter rotates the same number of inches per second as a circular rim 35 inches in diameter. If the smaller rim makes C revilutions per second, how many revilutions per minute does the larger rim makes in terms of C? Choose the correct choice from the following options: A) a) 48pi/C B) b) 75m C) c) 48C D) d) 24C E) e) C/75
distance covered by a circular wheel per sec* = 2*pi* r * n   where n is number of revolution   So we know the smaller rim makes C rev per sec so the inches coverd SR per sec = 28 * pi* C   the problem the say SR rotates the same number of inches as the LR.   The inches covered by the LR per sec = 35 * pi*Y   So equate both u will get Y = 4/5 c) 48C   Theis is in sec we need the answer in min so 48c) 48C   answer is c) 48C
