Answers to Section B (Theory)

1a. Define laminar flow.
Laminar flow is a smooth, orderly flow of a fluid in which adjacent layers slide past one another in parallel paths with little or no mixing (streamlined flow).

1b. Difference between laminar and turbulent flows.
Laminar flow: orderly layers, low mixing, usually at low speed/low Reynolds number; velocity at a point is steady.
Turbulent flow: irregular, with eddies and vortices, strong mixing, usually at higher speed/high Reynolds number; velocity fluctuates.

1c. Two applications of air and water flows.
Air: (i) Ventilation/air-conditioning duct design, (ii) Aerodynamics of vehicles/aircraft wings for reduced drag and lift generation.
Water: (i) Pipe networks/irrigation lines, (ii) Hydro-turbines for electric power.

2a. What is a linkage?
A linkage is a system of rigid bodies (links) joined by pivots/slider joints to guide and transmit motion and force in machines (e.g., four-bar, slider-crank).

2b. Explain linear motion.
Linear motion is movement in a straight line. Its key quantities are displacement, velocity and acceleration; examples include the to-and-fro (reciprocating) motion of a piston or a drawer sliding on rails.

2c. What is a speed ratio?
Speed ratio (velocity ratio) is the ratio of the input speed to the output speed of a mechanism (e.g., driver pulley/gear speed ÷ driven pulley/gear speed).

2d. What is a coupler?
A coupler connects two moving members to transmit motion (as in a four-bar mechanism), or connects two shafts (shaft coupling) to transmit power while accommodating slight misalignment.

3a. What is a gear?
A gear is a toothed wheel that meshes with another toothed wheel (or rack) to transmit motion and power, changing speed, torque and/or direction.

3d. List four types of gears.
Spur gears; Helical gears; Bevel gears; Worm and worm wheel (also: Rack and pinion).

3c. List two functions of clutches.
(i) Engage/disengage the engine from the gearbox for smooth starting and stopping; (ii) Allow gear changing without stalling (also provides overload protection in some machines).

4a. What is mechanical advantage?
Mechanical Advantage (MA) is the ratio of the load (output force) to the effort (input force): MA = Load ÷ Effort.

4b. List four devices that can make reversible rotary motion.
Clutches; Gear trains; Vehicle brakes (allow controlled start/stop and reversal in systems); Ratchets with reversing mechanisms (or reversible electric motors with gearing).

4e. State two uses of gears.
(i) To change speed and torque between shafts; (ii) To change the direction of rotation or translate rotary to linear motion (rack and pinion).

5a. What is an electric circuit?
An electric circuit is a closed path through which electric current flows, consisting typically of a source (battery/mains), conductors, loads (lamps/motors), and control/protection devices (switches, fuses).

5b. Difference between wiring tools and wiring materials (two examples each).
Wiring tools are instruments used to install or service wiring. Examples: Screwdriver, Combination pliers (also: wire stripper, test lamp).
Wiring materials are the components installed in the system. Examples: Cables/conductors, Switches (also: sockets, conduit, clips, tape).

5c. State four uses of electricity.
Lighting and illumination; Powering appliances and machines; Heating and cooking; Communication and ICT (radios, TVs, routers) (also: pumping water/industrial processes).
