Question 10

Gears

Answer 10

Gears are wheels with teeth which mesh to transmit rotary motion. When two or more gears mesh it is called a gear train. There are two types: Simple and Compound.

Question 11

Rack and pinion

Answer 11

Converts rotary motion into linear.

Question 12

Worm and wheel

Answer 12

The worm gear is usually found on an electric motor.
For one rotation of the worm the wheel rotates by one tooth.

Question 13

Bevel gears

Answer 13

Gears are cone-shaped. The angle is known as a bevel. They transfer rotary motion through 90 degrees.

Question 14

Linear

Answer 14

Straight Line motion

Question 15

Reciprocating

Answer 15

Straight Line – Backwards and Forwards

Question 16

Rotary

Answer 16

Round and round

Question 17

Oscillating

Answer 17

Swing backwards and forwards. (Rotary)

Question 18
