Q1:

Consider the following statements :
A : The load factor for live load is greater than that for dead load.
R : The live loads are more uncertain than dead loads.
Of these statements :

A Both A and R are true and R is the correct explanation of A

B Both A and R true but R is not a correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:B - Both A and R true but R is not a correct explanation of A

@ Chhaya: B is the right answer.

It needs a larger safety of factor. They may be fully or partially in place or not present at all and may change its location. Human, chair, table, computer, bed, furniture etc are live loads.

The factor for dead load (1.2) is lower than the factor for live load (1.6) because dead load is more predictable than live load. The load factors are all greater than 1.0
