Vocabulary
How do you say "rueda" in English?
Wheel
The point that supports a lever.
Fulcrum
All transmission of motion is either linear or rotary.
False: Some mechanisms transform rotary motion into linear motion, for example, a wheel, or a nut and bolt.
A pulley is an example of this type of mechanism.
Linear transmission
How do you say "palanca" in English?
Lever
The force of an object moving past and against another object.
Friction
The fulcrum is between the force and the resistance in class 1 levers.
True
Interlocking gears are an example of this type of mechanism:
Rotary transmission
How do you say "polea" in English?
Pulley
Motion that moves in a straight line
Linear transmission (of motion)
A mechanism can increase force and motion at the same time.
False:
If a mechanism increases force, it reduces motion. Similarly, if a mechanism increases motion, it reduces force.
A wheel is an example of this type of mechanism:
Rotary-linear
How do you say "cadena" in English?
Chain
Speed control
When the forces acting on opposite ends of a lever are equal, we say the lever is in equilibrium.
True
A ratchet is an example of this type of mechanism:
Direction control
How do you say "engranajes" in English?
Gears
The thing that provides a mechanism force and motion.
Input source
Friction does not effect the energy and work that mechanisms receive.
False: some energy is lost to friction and heat.
A brake (freno) is an example of this type of mechanism:
Speed control
