${?}^{}4\mathrm{.}24$ to $4\mathrm{.}30$ The nomenclature for the four$-$bar linkage

is shown in Fig. P$4\mathrm{.}24$; the dimensions and

data are given in Table P$4\mathrm{.}24$ to P$4\mathrm{.}30.$ Angu$-$

lar velocity ${}_2$ is constant for each problem

$($a negative sign indicates that the direction is

clockwise$).$ The dimensions of even$-$numbered

problems are inches and odd$-$numbered problems

are millimeters. For each problem, determine

${}_3,{}_4,{}_3,{}_4,{}_3,$ and ${}_4.$
