nches.

$4-25$ A pivot in a linkage has a pin as depicted in the figure whose dimension $a+-t_a$ is to be cstablished. The thickness of the link clevis is $1\mathrm{.}000+-0\mathrm{.}002$ in$.$ The designer has concluded that a gap of between $0\mathrm{.}004$ and $0\mathrm{.}14$ in will satisfactorily sustain the function of the linkage pivot.

In Prob. $4-25$ the dimensions are

$aN(1\mathrm{.}051,0\mathrm{.}0015)$ in $,bN(1\mathrm{.}000,0\mathrm{.}001)$ in
