CBoth statically determinate and indeterminate elastic structures
DNon-linear plastic structures only
The maximum bending moment in a fixed beam of span ‘L’ carrying a uniformly distributed load ‘w’ over entire span occurs at supports and equals:
Aw * L² / 8
Bw * L² / 12
Cw * L² / 24
Dw * L² / 16
The vertical stress increments under a point load on soil surface at depth ‘z’ directly along the load axis as per Boussinesq equation is proportional to:
A1 / z
B1 / z²
C1 / z³
D1 / sqrt(z)
According to Cassagrande’s plasticity chart, the A-line separating clays from silts is given by the equation:
AIP = 0.73 * (LL - 20)
BIP = 0.50 * (LL - 10)
CIP = 0.90 * (LL - 20)
DIP = 0.73 * (LL - 10)
In a unconfined compression test on a cohesive clay soil sample, the unconfined compressive strength (qu) is related to undrained cohesion (cu) by:
Acu = qu / 2
Bcu = qu
Ccu = 2 * qu
Dcu = qu / 5.7
An Isochrone in catchment hydrology is defined as a line connecting points on the catchment having equal:
ARainfall intensity
BTravel time of runoff to the catchment outlet
CElevation above sea level
DInfiltration capacity
According to Kennedy’s silt theory, the critical velocity (Vo) in a canal is proportional to flow depth (D) raised to the power:
A0.50
B0.64
C1.00
D1.76
The relation between Duty ‘D’ (in hectares/cumec), Delta ‘delta’ (in meters), and Base Period ‘B’ (in days) is:
Adelta = 8.64 * B / D
Bdelta = 8.64 * D / B
CD = 8.64 * delta / B
Ddelta = 864 * B / D
The maximum permissible concentration of nitrates (as NO3-) in drinking water to prevent Methemoglobinemia (Blue Baby Syndrome) in infants is:
A10 mg/L
B45 mg/L
C100 mg/L
D250 mg/L
