Q6: A cantilever beam having span ‘L’ m was subjected to a uniformly distributed load of
magnitude 8 kN/m for a distance of ‘0.6 L’ from the free end and two concentrated loads one of
magnitude 15 kN at a distance ‘0.25 L’ m from the free end while the other of magnitude ‘22’ kN at
a distance ‘0.6 L’ m from the free end respectively. It was observed that the maximum bending
moment acting on the beam is equal to (-369 kNm). Suggest a suitable span for the beam based on
the loading condition. How it will change the reaction at the fixed support? What happens to the
shear force and bending moment values at the fixed support, free end and at the center of the
beam? By plotting bending moment and shear force diagram for the beam briefly conclude the
relationship between the values for shear force and bending moment

A beam extends over a span of 7.3 m and an overhang (cantilever) to the right of the right support of 3 m (that is, the total length of the beam is 10.3 m.) The beam supports a service dead load of 18 t/m that does not include self-weight, and a service live load of 10 t/m. Assume the connection between the beam and the support is a simple pin or roller. . If self-weight is 1.512 , the height(h)...

A cantilever, 2.6 m long, carryinga uniformly distributed load w along the entire length, is propped at its free end to the level of the fixed end. If the load on the prop is then 30 kN, calculate the value of w. Determine also the slope of the beam at the support. If any formula for deflection is used it must first be proved. E = 210GN/m2; I = 4 x 10-6m4.
