The following statements are related to temperature stresses developed...
If slab in considered weightless it will result in its E value=0, thus, no temperature stresses.
If slab weight considered, during day the upper part of slab will be heated due to sunlight in comparison to lower slab. This leads to compressive stress at top and tensile stress at bottom. Exactly opposite that is tensile at top and compressive at bottom occurs during night.

Question number – 193
Forum Id – 609559
Solution: (a)
For dilution coefficient equal to 1
Weight of chlorine to be used/(square of discharge) = constant
32/(16*16) = x / (22*22)
x=60.5 kg/day

The following statements are related to temperature stresses developed...
Introduction:
Temperature stresses are developed in concrete pavement slabs due to the difference in temperature between day and night times. The presence or absence of restraint can affect the magnitude and distribution of these stresses. In this question, we are considering concrete pavement slabs with free edges, meaning there is no restraint.
Statement P:
The statement P states that the temperature stresses will be zero during both day and night times if the pavement slab is considered weightless.
Explanation of statement P:
When a concrete pavement slab is considered weightless, it means that there is no self-weight acting on the slab. In this case, the temperature stresses developed due to the difference in temperature between day and night times will be zero. This is because the absence of self-weight eliminates the compressive or tensile forces that would be generated by the weight of the slab. Therefore, statement P is true.
Statement Q:
The statement Q states that the temperature stresses will be compressive at the bottom of the slab during night time if the self-weight of the pavement slab is considered.
Explanation of statement Q:
During night time, the temperature of the pavement slab decreases, causing it to contract. If the self-weight of the slab is considered, it will resist this contraction, resulting in compressive stresses at the bottom of the slab. This is because the weight of the slab opposes the contraction and generates compressive forces. Therefore, statement Q is true.
Statement R:
The statement R states that the temperature stresses will be compressive at the bottom of the slab during day time if the self-weight of the pavement slab is considered.
Explanation of statement R:
During day time, the temperature of the pavement slab increases, causing it to expand. If the self-weight of the slab is considered, it will resist this expansion, resulting in compressive stresses at the bottom of the slab. This is because the weight of the slab opposes the expansion and generates compressive forces. Therefore, statement R is also true.
Conclusion:
Based on the explanations provided, the true statements are P and Q as they correctly state the behavior of temperature stresses in concrete pavement slabs with free edges. Therefore, the correct answer is option C, which includes both statements P and Q.
