Q3. 5. How to modify the natural frequencies and avoid resonance?
Ans. 
Natural frequencies can be modified by changing the material, shape, or boundary conditions of the structure.
• Changing the material properties can alter the natural frequencies of a structure.

• Modifying the shape of the structure can also change the natural frequencies.

• Adjusting the boundary conditions, such as adding or removing supports, can affect the natural frequencies.

Q1. Difference between explicit and implicit scheme?
Ans. 
Explicit scheme calculates future values using current values while implicit scheme uses future values to calculate current values.
• Explicit scheme is faster but less accurate than implicit scheme.

• Implicit scheme is more stable and accurate but slower than explicit scheme.

• Explicit scheme is used for problems with short time steps while implicit scheme is used for problems with long time steps.
