Q1. In reaction turbine-
(a) Flow can be regulated without loss
(b) Water may be allowed to enter apart of whole of wheel circumference
(c) The outlet must be above the tail race
(d) There is only partial conversion of available head to velocity head before entry to runner
Q2. Beam of uniform strength means
(a) A beam with uniform cross section
(b) A beam subject to same moment throughout
(c) A beam in which maximum bending stress is same at all sections
(d) A beam with same maximum shear stress at all section
Q3. According to Terzaghi, the net ultimate bearing capacity of clay is given by where: N_q N_r & N_c are bearing capacity factors, C- cohesion
(d) 1.2 C.N_c
Q4. The optimum depth of kor watering for wheat crop, is
(a) 13.5 cm
(b) 17.5 cm
(c) 19.5 cm
(d) 2.5 cm
Q5. On horizontal curve, if the pavement is kept horizontal across the alignment, then the pressure on the outer wheels will be …………..
(a) More than the pressure under inner wheels
(b) Less than pressure under inner wheels
(c) Equal to the pressure on inner wheels
Q6. Two-way slab is supported on _________ edges of wall
Sol. In a reaction turbine, there is only partial conversion of available heat to velocity head before entry to runner. Thus, at entrance to reaction turbine the fluid will have both pressure energy as well as kinetic energy.
Sol. Beam of uniform strength mean’s maximum bending stress is same at all section because section modules are inversely proportional to bending stress of beam.
Sol. According to Terzaghi
Net ultimate bearing capacity of clay.
▭(q_nu=C N_C )
For pure cohesive soil like clay
|Crop||Kor depth (in cm.)|
Sol. On a horizontal curve, if the pavement is kept horizontal across the alignment, then the pressure on the outer wheels will be more than the pressure on inner wheels.
Sol. ▭(ly/lx<2) (two-way slab)
⇒ In two-way slab, all four side of wall is fixed.
