Question 39
Open questionCENAT2 marksNeeds review
A prismatic cantilever prestressed concrete beam of span length,
m has one straight tendon placed in the cross-section as shown in the following figure (not to scale). The total prestressing force of 50 kN in the tendon is applied at
mm from the top in the cross-section of width,
mm and depth,
mm. If the concentrated load,
kN, the resultant stress (in MPa, in integer) experienced at point ‘Q’ will be

Employ stiffness matrix approach for the simply supported beam as shown in the figure to calculate unknown displacements/rotations. Take length,
m; modulus of elasticity,
N/mm²; moment of inertia,
mm⁴. 
The mid-span deflection of the beam (in mm, round off to integer) under
kN in downward direction will beLog in to check the answer
