Sample Practice Test Questions
Which of the following is not a characteristic of disc brakes?
uses brake shoes
Both drum brake and disc brake assemblies use friction to stop a car's wheels from turning but each do it in a slightly different way. A drum brake assembly uses a large iron drum attached to the wheel and brake shoes that press against the drum to slow the rotation of the drum and, consequently, the wheel. A disc brake assembly employs friction in the same way as a drum brake but instead uses a rotor, also attached to the wheel, and two brake pads that squeeze against the surface of the rotor.
A ramp is an example of which kind of simple machine?
inclined plane
An inclined plane is a simple machine that reduces the force needed to raise an object to a certain height. Work equals force x distance and, by increasing the distance that the object travels, an inclined plane reduces the force necessary to raise it to a particular height. In this case, the mechanical advantage is to make the task easier. An example of an inclined plane is a ramp.
The fuel injectors are fed fuel by the:
electric fuel pump
The electric fuel pump feeds pressurized fuel through a fuel filter to the fuel injectors via the fuel rail manifold. The fuel rail contains the fuel pressure regulator which ensures that the fuel injectors receive fuel at a consistent and known rate. Excess fuel bled off by the pressure regulator returns to the fuel tank through the fuel return line.
Which of these is not a type of fat?
cholesterol
Fats come in three types, saturated (meats, shellfish, eggs, milk), monounsaturated (olives, almonds, avocados), and polyunsaturated (vegetable oils).
The __________ converts pressure on the brake pedal to hydraulic pressure in the brake lines.
master cylinder
The master (brake) cylinder converts pressure on the brake pedal to hydraulic pressure in the brake lines.
The ovum and oviduct are part of which bodily system?
reproductive
Approximately every 28 days during female ovulation an egg (ovum) is released from one of the ovaries and travels through the oviduct (fallopian tube) and into the uterus. At the same time, the endometrial lining of the uterus becomes prepared for implantation.
4! = ?
4 x 3 x 2 x 1
A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
Respiration is the process by which __________ absorb oxygen and eliminate carbon dioxide.
blood cells
The respiratory system manages respiration which is the process by which blood cells absorb oxygen and eliminate carbon dioxide.
