Supports and Reactions

Q. A freely supported beam AB of span 4 m is subjected to a UDL of 1kN/m over the full span and a moment of 2kN-m at support A as shown in the figure. The resulting BM at mid-span C of the beam will be

1. 1 kN-m (sagging)
2. 1 kN-(hogging)
3. 2kN-m (sagging)
4. 2kN-m (hogging)

Q. What are the support reactions at the fixed end of the cantilever beam shown in the diagram below?

1. 120 kN, 120 kN-m
2. 120 kN, 240 kN-m
3. 240 kN, 120 kN-m
4. 120 kN, 60 kN-m

Q. A simply supported beam is loaded as shown in the given figure. The bending moment at E would be

1. 6 t-m (Sagging)
2. 4 t-m (Hogging)
3. 6 t-m (Hogging)
4. 4 t-m (Sagging)

Q. In a beam AB, support A is hinged and support B is on rollers as shown below. The directions of the reactions at A and B will be as in

1. 
2. 
3. 
4. 

Q. A rigid bar shown in the figure is hinged at A, is supported by a rod at B, and carries a load W at C.


The resistive force in the rod is

1. 0.5 W
2. 1. 0 W
3. 1.5 W
4. 2. 0 W
