TGPSC HMWSSB Manager 2015 Paper 2 · Question 98
Question 98 of the TSPSC Manager (Engineering), HMWSSB, 2015: Paper 2 (Civil Engineering) (1 November 2015). Try it first, then open the answer and explanation.
Analysis of trusses is based on the following assumptions. The correct combination of assumptions is ______. (i) All loads act at joints (ii) All joints are smooth friction less pin joints. (iii) Truss is made with material which is homogeneous, elastic and isotropic. (iv) The axis of all members is straight and their self weights are ignored.
- i, ii and iv
- i, ii, iii
- i, iv
- i, iii, iv
Show answer
Answer: (1) i, ii and iv
The ideal-truss assumptions are that loads act only at the joints, joints are frictionless pins, and members are straight with self-weight neglected, so every member carries only axial force; the material being homogeneous and isotropic is not one of the basic truss assumptions.
