shaft B is better than shaft A

shaft A is better than shaft B

both the shafts are equally good

none of these

The power transmitted by V-belts is less than flat belts for the same coefficient of friction, arc of contact and allowable tension in the belts

The V-belt drive is used with large centre distance

The V-belt may be operated in either direction with tight side of the belt at the top or bottom

The ratio of driving tensions in V-belt drive is more than flat belt drives
