Mechanisms

Question 1

linear motion

Answer 1

Movement in a straight line.

Question 2

Reciprocating motion

Answer 2

A back and forth movement.

Question 3

Oscillating motion

Answer 3

Movement backwards and forwards movement like a pendulum of a clock.

Question 4

Rotary Motion

Answer 4

circular movement

Question 5

Levers

Answer 5

Simple machines with an arm that moves around a fulcrum

Question 6

First order lever

Answer 6

the fulcrum is between the load and effort

Question 7

Second order lever

Answer 7

Load and effort on the same side of the fulcrum. load nearer to the fulcrum so less effort is required e.g. Wheelbarrow.

Question 8

Third order lever

Answer 8

fulcrum far right or far left load going up effort going down

Question 9

Mechanical Advantage (MA)

Answer 9

Ratio of the output force exerted by a machine to the input force applied to the machine.

Question 10

mechanical advantage formula

Answer 10

MA = output force (load) / input force (effort)

Question 11

Velocity Ratio (VR)

Answer 11

distance moved by effort/distance moved by load
