Mechanical components and devices

Question 1

What is a mechanical system?

Answer 1

Takes an input force and processes this to produce an output force. This could increase or decrease the magnitude of the force/motion covert or transfer the force/motion to the place it is needed.

Question 1

What is a mechanism?

Answer 1

A series of parts that work together to control forces and motion in a desired way.

Question 2

Name all 4 motion types?

Answer 2

Rotational speed
Linear motion
Oscillating motion
Reciprocating motion

Question 3

What is rotational speed?

Answer 3

Number of revolutions/time taken.

Question 4

What is linear motion?

Answer 4

Movement in a straight line.

Question 5

What is oscillating motion?

Answer 5

Moves back and forth in a circular path.

Question 6

What is a reciprocating motion?

Answer 6

Similar to linear motion, but also goes back and forth.

Question 7

Give the equation for linear speed?

Answer 7

Linear speed = distance travelled/time taken

Question 8

Give the equation for mechanical advantage?

Answer 8

MA = Load/Effort

Question 9

Give the equation for velocity ratio?

Answer 9

VR = Distance moved by effort/Distance moved by load

Question 10

What are the two thing a simple mechanism can do?

Answer 10

Increase the force, but reduce the distance moved.
Can reduce the force but increase distance moved.
