Q2. What is stress and how it can be measured?
Ans. 
Stress is a force acting on a material that causes deformation. It can be measured using techniques like strain gauges and load cells.
• Stress is a measure of the internal forces within a material resisting deformation.

• It is typically measured in units of force per unit area, such as Pascals or pounds per square inch.

• Common methods of measuring stress include strain gauges, load cells, and extensometers.

• Stress can be cat...read more

Q1. What is mean by kinetic energy
Ans. 
Kinetic energy is the energy possessed by an object due to its motion.
• Kinetic energy is directly proportional to the mass of an object and the square of its velocity.

• The formula for kinetic energy is KE = 0.5 * m * v^2, where m is the mass of the object and v is its velocity.

• Examples of kinetic energy include a moving car, a swinging pendulum, or a flying bird.
