Rigid jointed plane frame = 3m+r-3j.

The stable structure given so the answer is A.

(1)

M = 2j - 3.

Sunil Chhetri said: 7 years ago

2j-3 is for truss pin jointed.

3j-3 for rigid structure such as frame.

Raunak said: 4 years ago

This given answer is for stable truss structure.

And for frame m= (3j-r)/3.

Tanmoy said: 3 years ago

Here n = 2j-3.

Chris Depp said: 2 years ago

Generally, the structure is considered as a Plane if not specified, Hence.

m=2j-3.
