Question
A prismatic cantilever prestressed concrete beam of
span length, L = 1.5 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 de = 50 mm from the
top in the cross-section of width. b = 200 mm and
depth, d = 300 mm.
If the concentrated load, P = 5 kN, Find the resultant
stress (in MPa, in integer) experienced at point 'Q'.
