A system of simple machine with a VR of an AMA of 8, used to raise a load of 1000N through 20m high what is the in put work?
To determine the input work of a system, we can use the formula:
Input Work = Output Force × Output Distance
Let's calculate the input work using the given values:
Output Force (load) = 1000 N
Output Distance (height) = 20 m
However, you mentioned that the system consists of simple machines with a "VR of an AMA of 8." It seems like you are referring to the mechanical advantage (MA) of the system. The mechanical advantage of a system is defined as the ratio of the output force to the input force (MA = Output Force / Input Force).
Assuming the mechanical advantage (MA) is 8, we can rearrange the formula to solve for the input force:
Input Force = Output Force / MA
Input Force = 1000 N / 8 = 125 N
Now that we have the input force, we can calculate the input work:
Input Work = Input Force × Input Distance
However, you didn't provide the input distance in your question. To determine the input distance, we need more information about the system or the specific machine being used. Once you know the input distance, you can use the formula above to calculate the input work by multiplying the input force and input distance.
