1. A)Post A
The weight is distributed more on the side of post A, Therefore, it is holding
up the greatest part of the load.: Which post holds up the greater part of the load?
A- Post A
B- Post B
C- Both equal
D- Not clear
2. C)Neither of the other gears
Because of the way the gears are meshed, both gear 1 and gear 3 will move in
the opposite direction of gear 2.: Which of the other gears is moving in the same
direction as gear 2?
A) Gear 1
B) Gear 3
C) Neither of the other gears
D) Both of the other gears
3. A)A
Pulley A is the smallest gear. Therefore, it must turn faster (make more revo-
lutions per minute).: In this arrangement of pulleys, which pulley turns fastest?
A) A
B) B
C) C
D) D
4. A)Once
The single lobe on cam A will cause the setscrew to hit the contact point once
during the cam's revolution.: As cam A makes one complete turn in the figure
above, the setscrew will hit the contact point
A) Once
B) Twice
C) Three Times
D) Not At All
5. A)21
Since gear A has 15 teeth and gear B has 10 teeth, gear A is 1.5 the size of
gear B. Therefore, 14 x 1.5 = 21.: 1. When gear A makes 14 revolutions, how many
revolutions will gear B make?

A) 21
B) 17
C) 14
D) 9
6. B)Metal Spoon
Metal will feel coldest out of paper, wood, and the fabric of a blanket.: If all of
the following objects are at room temperature, which will feel coldest?
A) Book
B) Metal Spoon
C) Wooden Chest
D) Blanket
7. C)Air pressure on top of the liquid
The siphon works, in part, because of air pressure on the top of the liquid.: In
the illustration above, liquid is being transferred from the barrel to the bucket by
A) The vacuum at the lower end of the hose
B) The difference between the fluid volumes in the barrel and bucket
C) Air pressure on top of the liquid
D) Capillary action
8. C)Move downward until it reaches the floor
Newton's Law of Motion states that a body at rest will stay at rest unless
acted on by an outside force. Conversely, a body in motion stays in motion
unless acted on by an outside force. In this picture, both objects are at rest
(equilibrium). When an outside force is added to weight 1, the equilibrium
changes, moving this weight downward. Because the pulley has practically no
friction, the weight strikes the floor.: The figure above represents a pulley, with
practically no friction, from which two 10pound weights are suspended as indicated.
If a downward force is applied to weight 1, it is most likely that weight 1 will
A) Come to rest at the present level of weight 2
B) Move downward until it reaches with weight 2
C) Move downward until it reaches the floor
D) Pass weight 2 in its downward motion and then return to its present position
9. B)32 gallons per minute
