How much force is needed to lift the 10Kg weight?
A. 2 Kg
B. 5 Kg
C. 10 Kg
D. 20 Kg
Ans: The correct answer is (B) 5 Kg. In a double-pulley system, the force is
equal to the weight divided by two. It will require a 5 Kg force to lift a 10Kg
weight.
The smaller gear has 8 teeth, and the larger gear has 16 teeth. When the larger
gear makes 12 revolutions, how many revolutions will the smaller gear make?
See Picture
A. 8
B. 16
C. 18
D. 24
Ans: Question 2 Explanation: The correct answer is (D) 24. The gear ratio
here is 2:1, meaning that for every revolution of the larger gear, the smaller
gear revolves twice. If the larger gear revolves 12 times, the smaller gear will
revolve twice as many times.

B. The relationship between force and volume of a liquid.
C. The definition of pressure as pounds per square inch.
D. The manner in which liquids conform to their container.
Ans: The correct answer is (A) The amplification of force in a hydraulic
system.
The third principle of hydraulics is the basis for Pascal's Law and states that
when pressure is applied to a fluid, the pressure is transmitted evenly
throughout - in other words, how force is amplified within a hydraulic system.
An 80-lb child is sitting on one end of a seesaw. If another 80-lb child jumps
from a high platform onto the other end of the seesaw, what will happen?
A. The first child will stay stationary on the ground.
B. The second child will bounce off the seesaw into the air.
C. The first child will bounce off the seesaw into the air.
D. The first child will be lifted into the air, but remain seated.
Ans: The correct answer is (D) The first child will be lifted into the air, but
remain seated.
The force of the second child landing on the seesaw will propel the other end
of the seesaw into the air.
What is a vector quantity?
A. Gravity
