please solve this question clearly parts a and b

Solution

a) gear ratio in third gear = 24/22 = 1.09

For every one turn of the chainwheel in this gear, the freewheel makes 1.09 rotations. The measure of the angle through which the freewheel turns when the chainwheel completes 4 rotations is

= 4*(1.09)(360) = 1570.90 deg

b) gear ratio in fifth gear = 24/19 = 1.26

For every one turn of the chainwheel in this gear, the freewheel makes 1.26 rotations. The measure of the angle through which the freewheel turns when the chainwheel completes 3 rotations is

= 3*(1.26)*360

= 1364.21 deg

The angle freewheel turns is less than angle it moves in part (a)
