Ideaforge Technology Interview Questions and Answers

Q1. What is electrostatic discharge
Ans. 
Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects.
• ESD can occur when two objects with different electrical charges come into contact.

• Common examples include touching a metal doorknob after walking on a carpet.

• ESD can damage sensitive electronic components, such as computer chips.

• Preventive measures include using anti-static wrist straps and mats.

Q2. What is the maximum and minimum voltage of a Li-po battery cell
Ans. 
Li-po battery cells typically operate between 3.0V (minimum) and 4.2V (maximum) for optimal performance and safety.
• Minimum voltage: 3.0V - Discharging below this can damage the cell.

• Maximum voltage: 4.2V - Charging above this can lead to overheating and potential failure.

• Typical nominal voltage: 3.7V - This is the average voltage during discharge.

• Example: A standard 1-cell Li-po battery (1S) has these voltage limits.

Q3. 3. Tell me equations of motion?
Ans. 
The equations of motion describe the relationship between an object's position, velocity, acceleration, and time.
• 1. First Equation: v = u + at (final velocity = initial velocity + acceleration × time). Example: A car accelerates from 0 to 60 m/s in 5 seconds.

• 2. Second Equation: s = ut + 0.5at² (displacement = initial velocity × time + 0.5 × acceleration × time²). Example: A ball thrown upwards with an initial speed of ...read more

Q4. 4. How will you explain inertia to a child?
Ans. 
Inertia is the tendency of objects to stay still or keep moving unless something pushes or pulls them.
• Inertia means that things like to keep doing what they're already doing.

• If a toy car is rolling, it will keep rolling until it hits something or you stop it.

• If you have a ball resting on the ground, it won't move unless you kick it.

• The heavier an object is, the more inertia it has, making it harder to move or stop.

Q5. 5. What kind of loads act on street lamp pole?
Ans. 
Street lamp poles experience various loads including dead, live, wind, and seismic forces.
• Dead Load: The weight of the pole and the lamp itself.

• Live Load: Additional weight from snow, ice, or maintenance equipment.

• Wind Load: Forces exerted by wind pressure on the pole and lamp.

• Seismic Load: Forces due to ground motion during earthquakes.

Q6. 6. What do you mean by shear stress?
Ans. 
Shear stress is the force per unit area acting parallel to a material's surface, causing deformation or sliding.
• Shear stress is calculated using the formula: τ = F/A, where τ is shear stress, F is the applied force, and A is the area.

• It occurs in materials subjected to forces that cause layers to slide past each other, such as in a shear test.

• Examples include the stress on a beam when a load is applied perpendicular to...read more
