Q1. What are the forces acting on a rocket?
Ans. 
Forces acting on a rocket include thrust, weight, drag, and lift.
• Thrust is the force propelling the rocket forward.

• Weight is the force pulling the rocket down due to gravity.

• Drag is the resistance force acting opposite to the rocket's motion.

• Lift is the aerodynamic force generated by the rocket's shape to counteract weight.

• Other forces may include gravity, air resistance, and external forces.

Q2. Explain Stress strain curve
Ans. 
Stress strain curve shows the relationship between stress (force applied) and strain (resulting deformation) in a material.
• Stress strain curve is a graphical representation of how a material behaves under loading.

• It typically shows the stress on the y-axis and strain on the x-axis.

• The curve usually consists of three main regions: elastic deformation, plastic deformation, and fracture.

• Elastic deformation is the initial ...read more

Q3. Modes of heat transfer
Ans. 
Modes of heat transfer include conduction, convection, and radiation.
• Conduction: Heat transfer through direct contact between particles or objects (e.g. touching a hot pan)

• Convection: Heat transfer through the movement of fluids or gases (e.g. boiling water)

• Radiation: Heat transfer through electromagnetic waves (e.g. feeling the warmth of the sun)

Q4. What is viscosity
Ans. 
Viscosity is a measure of a fluid's resistance to flow.
• Viscosity is often described as the thickness or stickiness of a fluid.

• It is influenced by factors such as temperature and pressure.

• High viscosity fluids flow slowly, while low viscosity fluids flow quickly.

• Examples of high viscosity fluids include honey and molasses, while water has low viscosity.

Q5. Difference between ductile and brittle material using stress strain curve
Ans. 
Ductile materials exhibit large deformation before failure, while brittle materials fail suddenly without significant deformation.
• Ductile materials show a gradual increase in stress followed by necking before failure.

• Brittle materials have a steep stress-strain curve and fail abruptly without warning.

• Examples of ductile materials include metals like copper and aluminum.

• Examples of brittle materials include ceramics and
