What is the function of a vise in mechanical applications?
A. In mechanical applications, vises are used to arrest motion.
B. Vises are used to suspend quick movements, slowing the effects of conveyor belts.
C. In mechanical applications, vises are designed to assist movement
D. Vises are designed to function as a source of stability, much like how legs function
beneath a table.
A. In mechanical applications, vises are used to arrest motion.
The purpose of a vise is to arrest movement entirely, holding an object in a
single space. Vises are not used to forward movement, nor are they used to
simply slow down efforts. While vises can provide stability through their
ability to arrest movement, they do not function in the same way as table
legs, but must instead rely upon a base.
,Which of the following materials serves as a conductor?
A. Wood
B. Paper
C. Acrylic
D. Metal
Give this one a try later!
D. Metal
Metal is the sole material serving as a conductor; wood, paper, and acrylic
will all absorb and retain heat or cold rather than act as a conductor
Another word or phrase for false gravity is?
A. friction
B. tension
C. Newton's Law
D. centrifugal force
Give this one a try later!
D. centrifugal force
Centrifugal force is the only phrase accurately adhering to the notion of
gravity. While tension, Newton's Law, and friction are all aspects of this
portion of the test, centrifugal force is the only accurate representation of
false gravity.
Pulley systems require the synchronized movment of all pulleys. How can pulleys
escape this rule?
, A. Pulleys using twisted belts may move in opposing directions
B. To violate this rule, pulley system belts must be reversed
C. To violate this rule, pulley systems may be used in conjunction with gears
D. This rule cannot be effectively violated
Give this one a try later!
A. Pulleys using twisted belts may move in opposing directions
The design of pulleys prohibits the pairing of pulley and gear, and a simple
reversal of belts will result in synchronized reversal of all pulleys. To violate
this rule, a belt must be twisted
What are the potential functions of gear systems?
A. Gears possess a single function: transmitting motion
B. The potential functions of gears are: changes in direction, speed changes (both
increases and decreases), and motion transmission.
C. Gears may be used to change direction in machinery and can be used to increase
speed.
D. Gears are primarily used for making changes in speed, but may also be used to
instigate motion in machinery

B. The potential functions of gears are: changes in direction, speed changes
(both increases and decreases), and motion transmission.
Gears possess multiple functions, including speed and direction changes
and motion transmission. For this reason, the response involving three gear
uses is the only correct answer
