In a prestressed rectangular beam carrying two concentrated loads W at 33L from either end and provided with a bent tendon with tension P such that the central one-third portion of the tendon remains parallel to the longitudinal axis, the maximum dip ℎh of the tendon can be calculated using the principles of prestressed concrete. The maximum dip ℎh occurs at the midspan of the beam, where the bending moment due to the applied loads and the prestressing force is maximum. The tendon profile is typically parabolic under uniform load, and the maximum dip occurs at the midspan where the shear force is zero. The formula to calculate the maximum dip ℎh of the tendon in a prestressed rectangular beam is given by: h=8EIPL2 Where:
