Question 4
Maximum deflection at the mid-span of a simply-supported beam of span l, with uniformly distributed load (w) all over the beam span, and flexural rigidity EI, is (modulus of elasticity = E; moment of inertia of beam = I)
Question 5
The beam AC simply supported at A at C is pinned to a cantilever beam CD as shown in figure. Both beams have identical flexural rigidities EI. The vertical load of 8 kN acts at point B . The deflection of point B is:
Question 6
A propped cantilever is subjected to a concentrated load of 16 kN at the centre of the span. The length of beam is 4m. The flexural rigidity EI=4x102 kNm2. The reactions at the fixed end and simply supported end are:
Question 7
A steel bar ABC of uniform cross-section 100 mm2 is suspended vertically and loaded as shown in the figure. If the lower end of bar C does not move when loads are applied (neglect self-weight), then the value of force P is (Es=200 kN/mm2)
Question 8
If E is young’ modulus and I is moment of inertia, then the expression
at any section for a beam is equal to
