Q: Two flat beams AB and CD, lying in horizontal planes,
Two flat beams AB and CD, lying in horizontal planes, cross at right angles and jointly support a vertical load P at their midpoints (see figure). Before the load P is applied, the beams just touch ea...
See AnswerQ: A propped cantilever beam of a length 2L is loaded by a
A propped cantilever beam of a length 2L is loaded by a uniformly distributed load with intensity q. The beam is supported at B by a linearly elastic spring with stiffness k. Use the method of superpo...
See AnswerQ: A propped cantilever beam of a length 2L is loaded by a
A propped cantilever beam of a length 2L is loaded by a uniformly distributed load with intensity q. The beam is supported at B by a linearly elastic rotational spring with stiffness kR, which provide...
See AnswerQ: Determine the fixed-end moments (MA and MB) and
Determine the fixed-end moments (MA and MB) and fixed-end forces (RA and RB) for a beam of length L supporting a triangular load of maximum intensity q0 (see figure). Then draw the shear-force and ben...
See AnswerQ: A propped cantilever beam, fixed at the left-hand end
A propped cantilever beam, fixed at the left-hand end A and simply supported at the right hand end B, is subjected to a temperature differential with temperature T1 on its upper surface and T2 on its...
See AnswerQ: A continuous beam ABC with two unequal spans, one of length
A continuous beam ABC with two unequal spans, one of length L and one of length 2L, supports a uniform load of intensity q (see figure). Determine the reactions RA, RB, and RC for this beam. Also, dra...
See AnswerQ: Beam ABC is fixed at support A and rests (at point
Beam ABC is fixed at support A and rests (at point B) upon the midpoint of beam DE (see part a of the figure). Thus, beam ABC may be represented as a propped cantilever beam with an overha...
See AnswerQ: A propped cantilever beam has flexural rigidity EI = 4.5
A propped cantilever beam has flexural rigidity EI = 4.5 MN·m2. When the loads shown are applied to the beam, it settles at joint B by 5 mm. Find the reaction at joint B
