Question

100 POINTS PLS HELp

If the mechanical advantage of a machine is 4, what can you infer about the machine?


The output force is 4 times the input force.


The input force is 4 times the output force.


The output work is 4 times the input work.


The efficiency is 4%.

Answer 1

Answer: The mechanical advantage of a machine is 4. ... Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.
