Sample Practice Test Questions
Control arms connect a vehicle's suspension to the frame. The connection to the frame uses:
bushings
Control arms (upper and lower) connect a vehicle's suspension to the frame. The connection to the wheels is through ball joints which allow the control arms to turn and move up and down simultaneously. The frame connection uses bushings.
Which class of lever offers no mechanical advantage?
third
A third-class lever is used to increase distance traveled by an object in the same direction as the force applied. The fulcrum is at one end of the lever, the object at the other, and the force is applied between them. This lever does not impart a mechanical advantage as the effort force must be greater than the load but does impart extra speed to the load. Examples of third-class levers are shovels and tweezers.
Which of these is matter than cannot be separated into different types of matter by ordinary chemical methods?
element
An element is matter than cannot be separated into different types of matter by ordinary chemical methods.
Examples of primary consumers include:
cows
Primary consumers (herbivores) subsist on producers like plants and fungus. Examples are grasshoppers, cows, and plankton.
Regulation of heart rhythm occurs in:
medulla
Part of the brainstem, the medulla is the connection between the brain and the spinal cord. It controls involuntary actions like breathing, swallowing, and heartbeat.
This skeletal system is common in arthropods like insects, spiders, and crustaceans.
exoskeleton
An exoskeleton (external skeleton) is common in arthropods like insects, spiders, and crustaceans.
What is a framing square used for?
marking lines at a right angle
Rulers are used to both measure distance and to draw straight lines. Tape measures are flexible rulers made from cloth or metal and are useful for measuring longer distances and in tighter spaces. Both rulers and tape measures provide similar accuracy, commonly down to \({1 \over 16}\) or \({1 \over 32}\) inch. A steel framing square is made up of a shorter ruler (tongue) and a longer ruler (blade) that meet at a 90° (right) angle. A framing square is often used by carpenters when framing stairs and roofs.
