1) Question.
A simply supported beam ABC of length l carries a concentrated load P at an intermediate point B. If the slope at A is 0.75 times the slope at C, then the length of portion AB is equal to
Answer. -
2) Question.
If the deflection at the free end of a uniformly loaded centilever beam is 15 mm and the slope of the deflection curve at thefree end is 0.02 radian, then the length of the beam is
Answer. -
3) Question.
Slope at the end of a simply supported beam of span l with uniformly distrubted load w/unit length over the entire span is given by
where El is flexural rigidity of the beam
Answer. -
4) Question.
A beam ABC rests on simple support at A and B with BC as an overhang. D is centre of span AB. If in the first case a concentrated load P acts at C while in the second case load P acts at D, then the
Answer. -
5) Question.
A beam of overall length L rests on two simple supports with equal overhangs on both sides. Two equal loads act at the free ends. If the deflection at the centre of the beam is the same as at either end, then the length of either overhang is
