Question

what is the average torque of a rotor with I=50A,r=6cm,L=12cm,B=0.1T???
plzz reply fast frnds...

Answer 1

answer is 46mN...how??

Answer 2

is 46mN true??

Answer 3

Newton is force unit... what is correct answer

Answer 4

yes its true...t=2iblrcos(theta)
for max torque we use t=2iblr(cos(theta)=1)
wat shall we use for calculating avg torque??

Answer 5

soorry sorry its 46mN m

Answer 6

its not a question from mechanics...its a question from electromagnetics

Answer 7

wat are the limits of integration

Answer 8

did u get 46mN m??

Answer 9

in book the formula given was average torque=2IABN/pi

Answer 10

i got the ans.. average torque is limit 0 to T/2 of integaration (MBsinwt dt) /(T/2)....... where M=NIBA
the limit is 0 to T/2 as in 0 to T the total area is zero
