3. 3/4 in thick plate using longitudinal welds only where the length of the weld (L=10
in) and L = 1.25 W where W is the width of the plate.
4. Single angle where both legs are bolted to the support.
5. Single angle L8x8x1 with longitudinal welds (L = 9 in) on one leg
6. Channel C10x20 connected using one bolt only in the web
7. Single angle connected on one leg using transverse and longitudinal welds.

NOTE : As per guidelines. first 3 parts are solved. Request you to post remaining parts separately. Thanks
The U value stands for shear lag factor which refers to the reduction in shear capacity of a bolted plate due to the uneven distribution of shear stresses across the width of the plate.
