Name the Mechanical System in the image

• Gear train

• Chain drive

• Worm and Wheel

• Transmission

In the system shown the speed is

• increased

• constant

• dicreased

In the mechanical system shown, the direction of rotation in the output is

• In the same direction of the input

• In the opposite direction of the input

• increased

• decreased

Check the conditions fulfilled by the system shown

• output speed > input sepeed

• output torque > input torque

• output speed < input sepeed

• output torque < input torque

Torque is push or pull in a

• straight line

• circular direction

The movment you can find in the mechanical system of a bicycle is

• linear

• oscillating

• rotary

• reciprocating

Check the actions a mechanism can do

• Change the direction of the movement

• Change the type of movement

• Change the speed of the movement

• Change the amount of torque

An example of a gear train can be found in a

• hand drill

• motor

• swing

• see saw

The function of the idler gear is to

• increase the speed

• decrease the speed

• make the input and the output gears rotate in the same direction

• increase the torque

This is the mechanical system to move the paper in a printer What would happen if the idler stop working

• The paper will tear apart

• The paper will be stacked

• The printer will melt

• Ther is going to be friction in the gears
