About ideal mechanical advantage for an inclined plane

Click For Summary
SUMMARY

The ideal mechanical advantage (IMA) for an inclined plane is calculated using the formula 1/sin(theta). When the angle (theta) approaches zero, the concept of an inclined plane becomes irrelevant, as no lifting occurs. In such a scenario, both the IMA and actual mechanical advantage (AMA) equal 1, indicating no mechanical advantage is gained when moving an object across a flat surface. This discussion clarifies that the application of inclined plane principles is not applicable when the angle is zero.

the formula for the IMA for an inclined plane is 1/sin(theta)...right? But what if the angle was zero (which would mean it is not an inclined plane), then you wouldn't be able to divide by zero...so how would you get the IMA if the angle was zero?

I am very very confused about this...any help would be much appreciated.

the formula wat u have mentioned is applicable for an inclined plane... ie when we use an inclined plane for lifting a object of mass 'm' through a height 'h'. In general mechanical advantage is defined as the ratio of resistance force divided by the effort u apply... ie its the number of times the machine makes ur work simple.. if the angle is zero... it is clear that you don't need to lift the object... hence the application of inclined plane concept is ruled out...
 
Yeah, that's what I guessed at...so in this case the IMA and AMA would just be 1? since there wouldn't be any advantage or disadvantage to using a machine to drag the object across the surface?
