strural elements are respectively
Answer : Option DExplaination / Solution: No Explaination.
Q3.A person standing on the bank of a canal drops a stone on the water surface. He
notices that the disturbance on the water surface is not travelling upstream. This
is because the flow in the canal is
Answer : Option BExplaination / Solution: No Explaination.
Q4.A solid circular shaft of diameter d and length L is fixed at one end free at
the other end. Atorque T is applied at the free end. The shear modulus of the
material is G. The angle of twist at the free end is
Answer : Option BExplaination / Solution: No Explaination.
Q6.The flow of water (mass density = 100 kg/m3 and kinematic viscosity = 10-6 m2/s) in a commercial pipe, having equivalent roughness ks as 0.12 mm, yields an
average shear stress at the pipe boundary = 600 N/m2. The value of ks/δ' (δ' being the thickness of laminar sub-layer) for this pipe is
Answer : Option DExplaination / Solution: No Explaination.
Q8.A parabolic cable is held between two supports at the same level. The horizontal
span between the supports is L. The sag at the mid-span is h. The equation of
the parabola is where x is the horizontal coordinate and y is the
vertical coordinate with the origin at the centre of the cable. The expression for
the total length of the cable is
Answer : Option DExplaination / Solution: No Explaination.
Q10.A double cover butt riveted joint is used to connect two flat of 200 mm width
and 14 mm thickness as shown in the figure. There are twelve power driven rivets
of 20 mm diameter at a pitch of 50 mm in both directions on either side of the
plate. Two cover plates of 10 mm thickness are used. The capacity of the joint in
tension considering bearing and shear ONLY, with permissible bearing and shear
stresses as 300 MPa and 100 MPa respectively is
