Question

Two shafts &#39;A&#39; and &#39;B&#39; transmit the same power. The speed of shaft &#39;A&#39; is 250 r.p.m. and that of shaft &#39;B&#39; is 300 r.p.m. The shaft &#39;B&#39; has the greater diameter.-A-TrueB-False-B-False

APTITUDE CRACK · Accepted Answer

B False P=(2*&pi;*N*T/60). So for same power, NT=Constant. Therefore for less rpm more torque is transferred, so greater the torque greater is the diameter.
