# ISC Engineering Science Class 11 Syllabus 2023-24

This subject may not be taken with Physics. The syllabus is designed for candidates who have followed a course with a bias towards engineering. There is one paper of three hours duration of 100 marks.

Section A of the paper contains short answer questions, all of which are to be answered. Section B of the paper contains six questions of which you must answer five questions.

**1. Velocity and acceleration**. Laws of motion. Force, mass and acceleration. Acceleration due to gravity. Measurement of g, including examples of bodies moving with variable acceleration, treated graphically.

**2. Angular velocity and angular acceleration.**

**3. Composition and resolution of velocity.** Simple problem on projectiles, involving combined horizontal and vertical motion.

**4. Measurement and effects of force.** Equilibrium of concurrent forces in plane. Parallelogram, triangle and polygon of forces. Reaction, resultant and equilibrant. Bow's notation. Equilibrium of body on inclined plane. Treatment by graphical and mathematical methods.

**5. Moments.** Application to parallel forces, levers, vertically loaded rigid beams. Centre of gravity: experimental determination and calculation in simple cases. Its relation to stability.

**6. Pressure in liquids and its transmission.** Principle of Archimedes; floatation. Density and specific gravity of solids and liquids. Simple hydraulic pumps and jacks. Lift and force pumps; the siphon.

**7. Air Pressure.** Boyle's law. Barometers. Manometers and the Bourdon gauge. The bicycle pump. (Details of the Fortin barometer are not required.)

**8. Temperature and temperature scales.**

**9. Thermal expansion of solids, liquids and gases.** Coefficient of linear expansion of solids and coefficient of cubical expansion of liquids and gases. Charles' law. Absolute temperature. (Questions will not be set on apparent coefficients of expansion).

**10. Quantity of heat. Joule, Centigrade heat unit.** Specific heat capacity of solids and liquids; their determination. Change of state. Latent heats: their determination. Melting and boiling points; the effect of pressure. Heat as a form of energy. Calorific value of fuels (excluding experimental determination).

**11. Conduction, convection and radiation.**

**12. Conversion of heat to mechanical energy and vice versa.** Mechanical equivalent of heat, including any one method of determination.
