ASVAB Mechanical Comprehension Simple Machines Practice Test 3376
Inclined Plane
An inclined plane is a simple machine that reduces the force needed to raise an object to a certain height. Work equals force x distance and, by increasing the distance that the object travels, an inclined plane reduces the force necessary to raise it to a particular height. In this case, the mechanical advantage is to make the task easier. An example of an inclined plane is a ramp.
Which of the following will increase the mechanical advantage of this inclined plane?
lower the force acting at the blue arrow |
|
lengthen the ramp |
|
increase the force acting at the blue arrow |
|
shorten the ramp |
