A simply supported prestressed concrete beam of span 30 m. The initial stress is 1000 MPa. The slip in the jack during tensioning has been 3 mm. If $E_s = 200$ GPa, the loss of prestress due to anchorage is:

The axial force in the member PQ of the plane truss shown in figure is:

(Aromatic compound with an isobutyl side chain) $\xrightarrow[KOH, Heat]{KMnO_4}$ ?

What is the stiffness matrix for the beam shown in the figure (fixed at one end, guided roller at the other)?

A square pile of section $50 \, \text{cm} \times 50 \, \text{cm}$ and length $15 \, \text{m}$ penetrates a deposit of clay having $C = 5 \, \text{kN/m}^2$ and the adhesion factor $\alpha = 0.8$. What is the load carried by the pile through skin friction only?

Which of the following statements are true?

A. The proportioning of footing in sand is more often governed by settlement rather than by bearing capacity.
B. The pressure bulb profiles under a strip footing form as co-axially imaginable bulbs under its length.
C. Friction piles are also called as 'floating piles'.
