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
The key aspect about the bevel ger is
to increment the torque by 90°
to increment the speed by 90%
to transmit the movment in a 90° angle
The image shows the "first gear" in a manual transmission. From the following conditions check the ones that are true.
higher speed
higuer to torque
lower speed
lower torque
