Actually this is a question ask during my 1st interview..
I read earlier this & reply for condition i think 1 ) ans is solid shaft & for condition 2) Hollow shaft
But i do not find clear answer why ? what is the reason...
I have a two shaft 1) hollow shaft 2) solid shaft . both has same length.
Condition 1) If diameter of both this shaft is same, which shaft can transmit a more torque? how?
condition 2) If cross section area of both this shaft are same then which shaft can transmit more torque? how...
