In a system of two meshing spur gears, the driver has 12 teeth and the driven gear has 36 teeth. What is the gear ratio?
Answer: 1:3
The ratio of driver to driven teeth is 12:36, which simplifies to 1:3.
When two external spur gears mesh, how do their directions of rotation compare?
Answer: They rotate in opposite directions
Two externally meshing gears always turn in opposite directions.
A first-class lever has the fulcrum located where relative to the effort and load?
Answer: Between the effort and the load
In a first-class lever the fulcrum sits between the applied effort and the load.
Which simple machine is a wheel and axle BEST described as?
Answer: A rotating lever
A wheel and axle acts as a continuously rotating lever about its center.
Increasing the diameter of a pulley driven by a fixed-speed belt will do what to the pulley's rotational speed?
Answer: Decrease it
A larger driven pulley turns slower than a smaller one at the same belt speed.
A 100 lb load is lifted using a single movable pulley. Ignoring friction, what effort force is required?
Answer: 50 lb
A single movable pulley halves the effort, so 50 lb lifts the 100 lb load.
In a hydraulic system, pressure applied to a confined fluid is transmitted how?
Answer: Equally in all directions
Pascal's principle states pressure in a confined fluid transmits equally in every direction.
