The shear stress in a circular shaft of radius r subjected to torsion is maximum :
(ಡಿ) atcentre of shaft (13) at adistance /2 from centre of shaft

(C) atsurface of shaft (D)) at a distance 7/2 from surface of shaft

A simply supported rectangular beam is loaded transversely, the maximum tensile stress
develops at :

(ಹಿ) bottom fibre (B) top fibre

(ಲ) ‏٣‎ (3) no tensile stress

A surface vibrator for concrete compaction is preferred for all the following except :
(५) raft foundation (13) columns
() road pavements (1)) R.C.C. slabs

Maximum groas pressure which the soil can carry safely without shear failure :
(ಗೆ) Gross safe bearing capacity (B) Net safe bearing capacity
(5) Ultimate Bearing capacity (>) Net ultimate bearing capacity

Type of foundation suitable when the load is heavy and the soil is highly compressible :
(A) Mat foundation (B} Pile foundation
© Pier foundation (D) Well foundation

The property of cement tested by using Lechatelier apparatus :
(A) consistency (B) setting time

(0) compressive strength (D) soundness

The discharge through a V-notch varies as :
வ തു 013
மம തു 2

Hydraulic jump is used for :
(A) increasing the depth of flow (B) reducing the energy of flow

(C) decreasing the veloeity of flow (D) reducing the turbulence

An example of steady non-uniform flow is:
(ಹಿ) motion ए a river around bridge piers
(B) steadily increasing flow through a pipe
(C) steadily decreasing flow through a reducing section

(D) constant discharge through a long, straight tapering pipe
