Question

Consider the following statements with reference to a continuous beam supported at A, C and E for

which shear force

diagram is shown in the above figure. 

There is: 

1. A concentrated load acting at point B. 

2. A concentrated load acting at point D. 

3. A uniformly distributed load acting on the portion CE. 

Which of these statements are correct?
A.
1, 2 and 3
B.
1 and 2 only
C.
2 and 3 only
D.
1 and 3 only
Answer ( Option D)

1 and 3 only

Solution

Slope of SFD = Load intensity

Slope of SFD is constant in portion CE which shows a udl is acting on the portion CE.

Sudden change in SFD shows that a concentrated load is acting at the point.

Hence, statement 1 and 3 are correct.
