A planetary gear train shows the numbers of teeth of

$T_2=32,T_3=14,T_4=60.$ Determine the velocity ratio when

$(1)$ Sun gear $2$ serves as the input, Carrier $5$ serves as the output, and

Ring gear $4$ is braked.

$(2)$ Sun gear $2$ serves as the input, Ring gear $4$ serves as the output,

and Carrier $5$ is braked.

$(3)$ Ring gear $4$ serves as the input, Carrier $5$ serves as the output,

and Sun gear $2$ is braked.
