Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

What kind of mechanism is this?
Nut and bolt
It transforms circular motion into alternating motion and vice versa.  (Transformation of motion)
Rod and crank
it transforms circular motion into alternating linear motion. It is not a reversible mechanism.  (Transformation of motion)
Cam
It transforms circular motion into linear motion and vice versa. (Transformation of motion)

What kind of mechanism is this?
Chains
What kind of mechanism is this?
Pulleys and belts
It's a type of motion. This is alternating forward and backward motion in an arc.
Oscillating
It's a type of motion. This is motion in a circle. Its direction can be clockwise or anticlockwise.
Circular or rotational
It's a type of motion. This is forward and backward motion in a straight line.
Reciprocating rectilinear
This is a type of motion. This is motion in a straight line.
Rectilinear
Its purpose is to transmit and/or transform motion.
Mechanisms
This makes it easier to lift weight because you can use the weight of your body.
the pulley
Using this simple machine, you can lift heavy objects with little force.
the lever
The principle of this simple machine is used for motion and also to transmit motion. They were used to move heavy objects in the old days.
The wheel
It is also used to help lift very heavy objects and apply great amounts of pressure
Screw
With this simple machine, you can lift a heavy object with less force.
The inclined plane
Devices human use to complete tasks using less force.
