A plane truss consists of two linearly elastic, homogeneous, identical members, namely PQ and QR. Both members have length
, cross-sectional area
, and modulus of elasticity
. The members are inclined at
as shown in the figure. The truss has hinge supports at P and R. The translational degrees-of-freedom (u and v) are shown at joint Q. 
After application of the boundary conditions, the stiffness matrix of the truss becomes:

Consider the following statements with respect to rigid pavements:
Statement-1: Bottom-up cracking (BU) in rigid pavements is caused at the edge of the slab due to combined effect of single or tandem rear axle load and positive temperature differential.
Statement-2: Top-down fatigue cracking (TD) in rigid pavements is caused due to repeated cycles of axle loads and negative temperature differential.
The CORRECT option is:
