Sanyo Special Steel Manufacturing Senior Engineer Interview Questions and Answers

Speed is the rate at which an object covers distance. It is calculated by dividing distance by time.

• Speed = Distance / Time

• Units of speed include meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph)

• Speed can be constant or variable

Tension is the force experienced by a material when it is pulled or stretched.

• Tension is calculated using the formula T = F/A, where T is tension, F is force, and A is cross-sectional area.

• Tension can also be calculated using the formula T = E * (L/L0), where E is Young's modulus, L is the length of the material under tension, and L0 is the original length of the material.

• Tension is typically measured in units of Newto
