Answer 1

Correct answer is (b) Cramped joint

The best explanation: In Cramped joint, the cramps are used instead of dowels. The cramps are the pieces of non corrosive metal such as gunmetal, copper, etc. and their ends are turned down to a depth of about 40 mm to 50 mm. The length, width and thickness of the cramps vary from 200 mm to 300 mm, 25 mm to 15 mm and 5 mm to 10 mm respectively.
