1. Cantilever beam is appropriate if frame is short and thick.State whether the above statement is true or false
a) True
b) False
Explanation: Cantilever beam is appropriate if frame is long and slender
2. How many assumptions are made in cantilever method for solving a building frame?
a) 1
b) 2
c) 3
d) 4
Explanation: Regardless of methods, degree of indeterminacy is 3. So, there will always be 3 assumptions.
3. Where does neutral axis of column lie?
a) Vertical plane
b) Horizontal plane
c) Both of them
d) Neither of them
Explanation: As neutral axis passes through vertical columns which lie in horizontal axis (axis wise).
4. When a material returns to its undeformed original position after removal of load, then this behavior is called linear elastic material response.
a) True
b) False
Explanation: We have considered structures which show linear elastic material response
5.Which of the following causes greatest deflection for beams?
a) Internal axial force
b) Internal bending
c) Both causes equal deflections
d) External loads
Explanation: Internal bending causes greatest deflection for beam and frames.
6. In a truss, maximum deflection is caused by internal bending.
State whether the above statement is true or false
a) True
b) False
Explanation: Internal axial force causes most deflections in trusses.
7. In deflection diagrams, which of the following can’t have zero deflection in vertical direction?
a) Pin support
b) Roller support
c) Fixed support
d) Hinge
Explanation: Rest all can’t move from their initial positions as they all exert vertical force.
8.In deflection diagrams, which of the following can have zero angular deflection?
a) Pin support
b) Roller support
c) Fixed support
d) Hinge
Explanation: Only fixed support exerts moment at its point of contact.
9. What is the relation between angular deflections between two legs connected by a fixed-connected joint?
a) They are unequal
b) They are equal
c) Can’t say
d) They don’t show angular deflection
Explanation: Since it is a fixed joint, they can’t have a relative angular deflection in between them.
10. What is the relation between angular deflections between two legs connected by a pin-connected joint?
a) They are unequal
b) They are equal
c) Can’t say
d) They don’t show angular deflection
Explanation: Since it is a pin joint, they can have a relative angular deflection in between them.
