The beam has a constant flexural rigidity, and is subjected to the external moments of magnitude M at one-third spans, as shown in the figure. Which of the following statements is/are TRUE?

Ques 54 Structural Analysis

An idealised bridge truss is shown in the figure. The force in member $U_{2}L_{3}$ is _______ KN (round off to one decimal place).

Ques 55 Structural Analysis

The cross-section of a girder is shown in the figure (not to scale). The section is symmetric about a vertical axis (Y-Y). The moment of inertia of the section about the horizontal axis (X-X) passing through the centroid is _______ cm⁴ (round off to the nearest integer).

Ques 56 Structural Engineering

Consider a doubly reinforced RCC beam with the option of using either Fe250 plain bars or Fe500 deformed bars in the compression zone. The modulus of elasticity of steel is 2x10⁵ N/mm². As per IS456:2000, in which type(s) of the bars, the stress in the compression steel ($f_{sc}$) can reach the design strength (0.87$f_{y}$) at the limit state of collapse?

(A) Fe250 plain bars only
(B) Fe500 deformed bars only
(C) Both Fe250 plain bars and Fe500 deformed bars
(D) Neither Fe250 plain bars nor Fe500 deformed bars

Ques 58 Surveying

The direct and reversed zenith angles observed by a theodolite are 56^o00'00" and 303^o00'00" respectively. What is the vertical collimation correction?

Ques 59 Surveying

A student is scanning his 10 inch x 10 inch certificate at 600 dots per inch (dpi) to convert it to raster. What is the percentage reduction in number of pixels if the same certificate is scanned at 300 dpi?

Ques 60 Surveying

Trigonometric levelling was carried out from two stations P and Q to find the reduced level (R.L.) of the top of the hillock, as shown in the table. The distance between Stations P and Q is 55 m. Assume Stations P and Q, and the hillock are in the same vertical plane. The R.L. of the top of the hillock (in m) is _______ (round off to three decimal places).

Ques 61 Transportation Engineering

G₁ and G₂ are the slopes of the approach and departure grades of a vertical curve, respectively. Given |G₁| < |G₂| and |G₁| ≠ |G₂| ≠ 0
Statement 1: +G₁ followed by +G₂ results in a sag vertical curve.
Statement 2: -G₁ followed by -G₂ results in a sag vertical curve.
Statement 3: +G₁ followed by -G₂ results in a crest vertical curve.
Which option amongst the following is true?
