### Mechanical Aptitude 3 - Gears 1.    If the driven gear has 24 teeth and the driver gear has 8, then the driven gear?  Turns at same speed as of driver gear Turns three times slower than the driver Turns three times faster than the driver Actually driver gear moves slower 2.    For gear ratio of 3 - to - 1, if input torque is 100 Newton Meters ( unit of torque measurement in the SI system) then output torque is?  1/3 times i.e. 33.33 Newton Meters. 3 times i.e. 300 Newton Meters. It has no effect on output torque. Two answers are correct 3.    When three gears are in mesh, the central gear (B) is called?  Connecting gear Intermediate gear Idler gear Two answers are correct 4.    The idler gear transfers’ movement between the input and output gears, and?  Has no effect on the ratio Has no effect on the torque multiplication Torque and ratio remain unchanged All answers are correct 5.    Adjacent Gears always move in__________?  Clockwise Opposite Same Anti clockwise
