Question 1: Brake shoes

Answer:

curved friction devices that push against inside of brake drum slow wheels down when brakes are applied.They are mounted on a stationary backing plate

Question 2: Ball bearings

Answer:

small rotating spheres that reduce friction by changing sliding motion into rolling motion

Question 3: Cylinder Head

Answer:

located above the piston, it houses the combustion chamber, the intake and exhaust valves, and the intake and exhaust ports.

Question 4: Volatile Organic Compound

Answer:

Organic chemicals and petrochemicals that emit vapors while evaporating. In paints, VOC generally refers to the solvent portion of the paint which, when it evaporates, results in the formation of paint film on the substrate to which it was applied.

Question 5: Coil springs

Answer:

springs that are attached to a tightly woven webbing of rubber and metal, linen, jute, or synthetic; webbing is stretched across and attached to the bottom of the frame and serves aas the base for the springs which are then tied together at the top in at least 8 places per spring

Question 6: Diode

Answer:

A device that permits current to flow through it in only one direction.

Question 7: Rack-and-pinion

Answer:

is connected to the steering wheel, turns wheels by having a pinion gear mesh with a toothed rack

Question 8: Roller bearings

Answer:

Bearings with rolling elements in the shape of cylinders or tapered cylinders or needles; they have a greater load-carrying capacity but more friction than ball bearings of similar size.

Question 17: Starter motor

Answer:

the battery is connected to a large direct current motor called a _______.

Question 18: Idler Gear

Answer:

A gear positioned between the driver and the driven gear used to change rotational direction.

Question 19: Intake Stroke

Answer:

The piston moves away from the cylinder head, the intake valve opens, and a combustible fuel and air mixture is drawn into the cylinder.

Question 20: Drive Train

Answer:

Transmits power from the engine to the vehicle's drive wheels.
