down more easily

autoclave

2 False
5. Which one of the following statements is true?
1 The effective height is the length used for calculation of the of the Poisson’s ratio

wires
4 None of the above
5 All off the above

1 True
2 False
7. A possible solution to a cantilever problem is to provide a foundation pad at the settlement that is large enough resist the deflection.

Solution
1. The aggregate used in concrete bricks could be expanded clay, exfoliated vermiculite and sawdust or wood shavings.
2. Clinker bricks are calcium silicate bricks is a false statement
3. Concrete bricks composed of cement, stone, sand and water ( as Adobe bricks consists of other components also, Klin burned bricks are not passed trough Autoclave, Calcium Silicate bricks are autoclaved).
4. True
5. A wall tie is the welded fabric made up of 2 hard drawn wires, held apart by cross wires
6. False
7. True
8. False
9. True
10. The shear span is the ratio of the max design bending moment to the maximum design load ( as a column is a compression member, the effective length of which exceeds 3 times the least lateral dimenson and option 2 may not be true all time)
