what is the efficiency and mechanical advantage of inclined plane?

Question

I would really appreciate it if you could tell me the mechanical advantage and efficiency of all the simple machines

Answer 1

The efficiency for every simple machine will vary greatly depending on several factors (incline angle, temperature, friction, altitude). The mechanical advantage is pretty obvious for any simple machine...that's why we use them! Think about, you use a lever to get more torque, a wheel to...well you should be able to figure the rest out. Open your textbook.

Answer 2

Efficiency depends on coefficient of friction between surface and what is moving on it. Work to raise load is force to push times length along incline. Theoretical is weight of object times height. Efficiency is second / first. If coefficient is zero, effciency is = 1. The advantage is that the force required to push is lower but you have to push a longer distance, instead of just lifting object.

Same as with systems of pulleys. A screw is just a coiled incline plane.

Answer 3

It simply spreads the energy required to lift a vertical load over a greater distance. Instead of lifting straight up, it takes less power to move the load up a ramp, a bit at a time. The longer (shallower) the ramp, the less lift is needed.

A screw is an example of a ramp, wrapped around a shaft. A little force, turrning the screw translated to a lot of force at the working end.

I am not going to do all your homework for you, but most of the simple tools you are researching use one similar principal. To spread the work required over a greater distance to do heavier work at the other end. Pulley, lever, etc.

Answer 4

Too many simple machines out there to possibly list all the advantages on here

Answer 5

if you are interested to displace to any body in less effort then it will much easer from inclined plane than horizontal plane.
