Q2. Chok kai hai? What difference between series and parleller combinations
Ans. 
Series and parallel combinations are two ways of connecting components in an electrical circuit.
• In a series combination, components are connected end-to-end, so the same current flows through each component. The total resistance of the circuit is the sum of the individual resistances.

• In a parallel combination, components are connected side-by-side, so the voltage across each component is the same. The total resistance ...read more

Q1. Micro meter least count
Ans. 
Micro meter least count is the smallest measurement that can be read on a micrometer.
• Least count is determined by the number of divisions on the micrometer scale and the pitch of the screw

• It is usually 0.01 mm or 0.001 mm for most micrometers

• The least count is important for accurate measurement and should be considered when selecting a micrometer for a specific application

Q2. Vernier caliper least count
Ans. 
Vernier caliper least count is the smallest measurement that can be read on the scale of the caliper.
• The least count of a vernier caliper is usually 0.02 mm or 0.05 mm.

• It is determined by dividing the smallest division on the main scale by the number of divisions on the vernier scale.

• For example, if the smallest division on the main scale is 1 mm and there are 20 divisions on the vernier scale, the least count would be

Q1. How to decide number of modes to extract in modal analysis?
Ans. 
The number of modes to extract in modal analysis is typically determined based on the desired accuracy of the analysis and the computational resources available.
• Consider the complexity of the structure being analyzed - more complex structures may require more modes to be extracted

• Take into account the desired accuracy of the analysis - higher accuracy may require more modes to be extracted

• Evaluate the computational res...read more

Q1. How fatigue anlysis of weld is performed ?
Ans. 
Fatigue analysis of weld is performed by applying cyclic loading to the weld and analyzing stress concentrations.
• Apply cyclic loading to the weld to simulate real-world conditions

• Analyze stress concentrations at critical points using finite element analysis

• Calculate fatigue life based on stress levels and material properties

• Consider factors such as weld geometry, residual stresses, and material defects

• Use standards lik
