Chapter 12 : Support Reactions 243
QUESTIONS
- What are various type of loadings? Distinguish clearly between uniformly distributed
load, uniformly varying load and triangular load. - Define the term ‘support reaction’. Describe the analytical as well as graphical methods
for finding out the support reactions of a beam carrying vertical loads only. - State the direction of a support reactions in the case of (a) simply supported end (b)
hinged end and (c) roller supported end. - Write the assumptions, which are made, while finding out the reactions of a beam or a
frame having both ends fixed.
OBJECTIVE TYPE QUESTIONS
- In a simply supported beam carrying triangular load, the reactions can not be vertical
(a) True (b) False- An overchanging beam with downward loads............have one of its reaction upward and
the other downward.
(a) can (b) can not - The reaction at the roller supported end of a beam is always
(a) vertical (b) horizontal (c) none of the above- If the reaction of a beam, at one of its supports is the resultant of horizontal and vertical
forces, then it is a
(a) simply supported end (b) roller supported end (c) hinged end - A couple acting at the mid-point of a simply supported beam has some horizontal and
vertical components.
(a) Agree (b) Disagree. - A truss hinged at one end, supported on rollers at the other, is subjected to horizontals
load only. Its reaction at the hinged end will be
(a) horizontal (b) vertical
(c) resultant of horizontal and vertical.
ANSWERS
