PT2-Tests 2 & 3

QuestionAnswer
The input gear in the gear box on a bulldozer has 16 teeth. The output gear has 168 teeth. The output gear speed is 28 rpm. This causes the tractor to move forward at 3 mph. How fast is the input gear rotating? IMA=No/Ni IMA =wi/wo 294 rpm
The ideal mechanical advantage (IMA) of a rotational force transformer is always: Equal to or greater than the actual mechanical advantage.
The actual mechanical advantage (AMA) of a belt drive-system equals: The ratio of torques (To/T1)
How does the third and fifth gear of a simple gear train compare if both gears have an equal number of teeth? Rotation remains the same, no change in torque.
When there is an increase in torque on the output pulley of a belt drive system, the angular speed of the output pulley: Decreases
A decrease in angular speed on the output pulley of a belt drive system causes the amount of torque on the output pulley to: Increase
If the efficiency of a gear drive is 80% and the IMA is 20, what would be the actual mechanical advantage? 16.0
In a pressure intensifier, while the area of the piston faces decrease from input piston to output piston, output pressure from the input to the output side of the intensifier: Increases
Work input equals work output in a hydraulic jack is expressed as: P1*V1=po*Vo
What remains the same from input to output pressure intensifier? Force and piston movement
The ideal mechanical advantage of a jack is given as: IMA=D1/Do
What increases from input to output in a hydraulic jack? Force and piston area
What decreases from input to output in a hydraulic jack? Piston movement
