Two plates of thickness 16mm 14mm are

to be jointed by a butt weld. The joint is

subjected to tensile force 280 KN. Due to

some reasons effective length of weld that

should be provided was 175mm only Check

the safety of joint

if 1) Single V-Butt Weld is provided.

2) Double V-B utt Weld is provided. 4

The length of the strut between the intersection

at each end is 3.0m. Calculate the strength of

the strut if

i) It is connected by 2 rivets at each end.

ii) It is connected by 1 rivet at each end.

iii) It is welded at each end.
