A $60"$ or delta strain gauge rosette is mounted on a structure as shown in Fig.Q$,2.$

The strain readings measured ty the three individus gauges, a$,$ b and c when the structure is loaded are indicated on this figure.

use the strain transformation equations to derive values of these two strains from the strains messured by the gauges a$,$ b and c$.$

For the delta rosette shown

Please enter the vatue in ut of the shear strain, Yxy

Determine values of the principal strain, e$1,$e$2$

Determine the orientation of the plane on which the first principal strain acts, relative to the vertically aligned gauge answer the angle theta$1$ in degree:
