1. Describe how a Class 2 lever functions and provide an example.
A Class 2 lever amplifies force by positioning the load between the
fulcrum and the effort, such as a wheelbarrow.
A Class 2 lever has the fulcrum between the load and the effort, like a
seesaw.
A Class 2 lever is used only in mechanical systems involving pulleys.
A Class 2 lever requires equal forces on both sides to function.
2. The formula for calculating head pressure is _________.
rise x .707 psi
elevation in feet % .433
elevation in feet x .433
rise x 1.414 psi
3. What are the three classes of levers based on the positions of the fulcrum,
resistance, and effort?

First class, second class, third class
Static, dynamic, kinematic
Input, output, fulcrum
4. What is the formula used to calculate head pressure in fluid mechanics?
P = F/A
, P = ρgV
P = ρgh
P = mgh
5. What is the definition of mechanical advantage in the context of a pulley
system?
The speed at which a pulley can operate.
The ratio of the output force to the input force in a mechanical
system.
The weight of the pulley itself.
The total distance a pulley can lift an object.
6. If a block and tackle system consists of four pulleys, how does this
configuration affect the force required to lift a weight compared to using a
single pulley?
It increases the force required to lift the weight by a factor of four.
It reduces the force required to lift the weight by a factor of four.
It doubles the force required to lift the weight.
It has no effect on the force required to lift the weight.
7. If a water tank has a head of 10 meters, what would be the approximate
pressure at the bottom of the tank in Pascals, assuming standard gravity?
9,800 Pascals
98,100 Pascals
10,000 Pascals
1,000 Pascals
, 8. What is the mechanical advantage of an ideal rope and pulley system?
1
2
3
0.5
9. What is the primary function of a lever in mechanical systems?
To transmit power
To support weight
To measure pressure
To amplify forces
10. Describe how a block and tackle system improves mechanical advantage.
A block and tackle system is used solely for horizontal movement.
A block and tackle system works by increasing the speed of the load
being lifted.
A block and tackle system only functions with a single rope.
A block and tackle system improves mechanical advantage by
distributing the load across multiple ropes, reducing the effort
needed to lift heavy objects.
11. Describe how water head pressure is calculated and what factors influence it.
Water head pressure is affected by atmospheric pressure and the
color of the water.
Water head pressure is determined by the temperature of the water
and the volume of the container.
