a) 6754.68/EI
b) -6754.68/EI
c) 4503.12/EI
d) -4503.12/EI
View Answer

Answer: a
Explanation: Solving the system of equations for lateral displacement results in the value 6754.68/EI.

8. In beam AB, initially, moments m_AB and m_BA are assumed to be clockwise. Under this assumption, what will be the direction of shear at point A in beam AB?

a) rightward
b) leftward
c) can’t say
d) value will be 0
View Answer

Answer: b
Explanation: By separating out the beam and conserving moment about point B, the shear at point A will be leftward.
