Answer 1

Answer:

Distribution Method if support B and C sink by 3mm and 5mm respectively take E = 200 ... b) A three hinge parabolic Arch ACB of span 30 met. has its supports at ... Sample 1 : X = 30, Y = 80, Z = 90

Answer 2

1. A set square is a right-angled plate that is triangular in shape.

2. it is used for drawing lines mainly for engineering and technical purposes.

3. it provides a straight edge at right angles or other angles particular to the baseline

4. One pair of the set squares has 2 of these triangular planes. One of the planes has the measurement of 90-45-45 and the second plane has the measurement of 30-60-90

5. So, the correct answer is (A) 30-60-90
