Which of the following is NOT an example of a typical stress distribution diagram at the base of a circular chimney?
By which one of the following methods is an approximate quick solution possible for frames subjected to transverse loads?
Consider the following statements:

1. The distribution factor for fixed and pin support is zero since any moment is resisted by an equal and opposite moment within the support and no balancing is required.

2. In the case of pinned supports, the distribution factor is equal to 1.0 since 100% of any applied moment must be balanced and a carry-over of 1/2 × the balancing moment transferred to the remote end at the internal support.

Which of the above statement(s) is/are correct?
Assertion (A) : Method of moment distribution is classifiable as a force method.
Reason (R) : The method consists of computing end moments due to end rotation of the member.
What are the bending moments at the ends A and B of a uniform beam AB fixed in direction and position at A and B when acted upon by two concentrated loads at 1/3rd span as shown in the figure above?
