Q1.The system that uses the Sun as a source of electromagnetic energy and records the
naturally radiated and reflected energy from the object is called
Answer : Option CExplaination / Solution: No Explaination.
Q4.The staff reading taken on a workshop floor using a level is 0.645 m. The inverted staff
reading taken to the bottom of a beam is 2.960 m. The reduced level of the floor is
40.500 m. The reduced level (expressed in m) of the bottom of the beam is
Answer : Option AExplaination / Solution:
RL of bottom of beam = 40.5+2.96+0.645 = 44.105m
Q5.A 4 m wide rectangular channel, having bed slope of 0.001 carries a discharge of
16 m3 /s. Considering Manning's roughness coefficient = 0.012 and g = 10 m/s2 , the
category of the channel slope is
Answer : Option BExplaination / Solution:
Given discharge (Q) = 16 m3 / sec.
Q6.A two lane, one-way road with radius of 50 m is predominantly carrying lorries with
wheelbase of 5 m. The speed of lorries is restricted to be between 60 kmph and 80
kmph. The mechanical widening and psychological widening required at 60 kmph are
designated as wme,80 and wps,80, respectively. The mechanical widening and
psychological widening required at 80 kmph are designated as and wme,80 and wps,80, respectively. The correct values of wme,60, wps,60 respectively are
Q7.A fine grained soil is found to be plastic in the water content range of 26-48%. As per
Indian Standard Classification System, the soil is classified as
Answer : Option DExplaination / Solution:
Soil is plastic in range of 26% to 48%. So, plastic limit =26%, liquid limit = 48%
Since 35%
