Various stresses in jointed plain concrete pavement with slab size of 3.5 m × 4.5 m are denoted as follows:

Wheel load stress at interior = $S_{wl}^i$
Wheel load stress at edge = $S_{wl}^e$
Wheel load stress at corner = $S_{wl}^c$
Warping stress at interior = $S_t^i$
Warping stress at edge = $S_t^e$
Warping stress at corner = $S_t^c$
Frictional stress between slab and supporting layer = $S_f$

The critical stress combination in the concrete slab during a summer midnight is

A

$S_{wl}^c + S_t^c$

B

$S_{wl}^e + S_t^e + S_f$

C

$S_{wl}^e + S_t^e - S_f$

D

$S_{wl}^c + S_t^c + S_f$

A horizontal curve of radius 1080 m (with transition curves on either side) in a Broad Gauge railway track is designed and constructed for an equilibrium speed of 70 kmph. However, a few years after construction, the Railway Authorities decided to run express trains on this track. The maximum allowable cant deficiency is 10 cm.

The maximum restricted speed (in kmph) of the express trains running on this track is _______________ (rounded off to the nearest integer).

A vertical summit curve on a freight corridor is formed at the intersection of two gradients, +3.0% and −5.0%.

Assume the following:
- Only large-sized trucks are allowed on this corridor
- Design speed = 80 kmph
- Eye height of truck drivers above the road surface = 2.30 m
- Height of object above the road surface for which trucks need to stop = 0.35 m
- Total reaction time of the truck drivers = 2.0 s
- Coefficient of longitudinal friction of the road = 0.36
- Stopping sight distance gets compensated on the gradient

The design length of the summit curve (in meters) to accommodate the stopping sight distance is _____ (rounded off to 2 decimal places).
