Question
A 5 kg mass is suspended at the free end of an overhanging massless beam, having a pin support and a roller support, as shown in the figure below. Young’s modulus of the material of the beam is 200 GPa and area moment of inertia of the beam is m. The natural frequency of the beam in rad/s is

Correct answer
(A) 10
Solution
1.Calculate the equivalent stiffness () at the free end C:
- For an overhanging beam with span and overhang , the deflection at the free end due to a load is .
- Here, , , , and .
- .
- Stiffness .
- , where .
- .
