What is the mechanical advantage of a machine that requires 30 end of input force to provide 15 end of output force?

The mechanical advantage (MA) of a machine is calculated by dividing the output force by the input force. In this case, the input force is 30 units and the output force is 15 units. Thus, MA = output force / input force = 15 / 30 = 0.5. This indicates that the machine does not provide a mechanical advantage, as it requires more input force than the output force it delivers.
