Solution

Coordinate sof a1 , b1 , B2 xa1 =000 Xb1 =1.721 Xa2 =2.656 Xb2 =5.065

ya1 =000 yb1 =1.750 ya2 =0.751 yb2 =-0.81

design chices : link lengh , link 3 L =5.000 link4 l4 =2.000

following notation used in exampe 3-2 . change the label s on points A and B to C and D respectively. draw the link Cd in its two dsired positions C1D1 and C2 D2 using the given coordinates.

Draw construction lines from C to C2 and D1 to D2

bisect line C1C2 and line d1D2 and extend itheir perpendicuar bisectors to intersects at O4.

using the length of link 4 as a radius , draw an arc about O4 to the bth lines O4c1 and O4C2 . label the instructions aas B1 and B2
