Question

Consider the loaded beam shown in the given figure :


Assertion (A): The deflection at the free end C is 'a' times the slope at A.
Reason (R): The elastic curve for the overhang portion AC or BD is a straight line tangential to the elastic curve at A and B.

• A. both A and R are true and R is the correct explanation of A
• B. both A and R are true but R is not a correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is A both A and R are true and R is the correct explanation of A

Since there is no load on portion CA so the elastic curve is a straight line and deflection at free end is 'a' times the slope at A.
