Problem $1$:

Design a fourbar linkage using Solidworks that is

capable of positioning the $70$ mm $-$long coupler at the

three positions shown at right $($all dimensions shown

are in mm $).$

Report all link dimensions $($including ground$)$ and

provide screenshots of the linkage positioned with the

coupler at the three positions shown, as well as two intermediate positions. Also, indicate if

the linkage is Grashof or non$-$Grashof. Show your work for this determination.

Problem $2$:

Using Solidworks, add a driver dyad that sweeps the linkage of Problem $1$ from Position $1$ to

Position $3$ and back. The linkage should have a time ratio of $0\mathrm{.}8.$

Report all link dimensions of your driver dyad $($including ground$)$ and show screenshots of the

linkage positioned at both extreme limits as well as an intermediate position. Show all

calculations for your driver dyad crank and coupler length, as well as you calculations for the

construction angle, $.$
