it means the mechanical advantage is greater.
mechanical advantage= output force over input force times 100
friction affects the M.A in a simple machine.
The answer is mechanical advantage, not efficiency!
80 Is the Output force
Actual mechanical advantage is the ratio of the output force to the input force in a simple machine or system. It is a measure of how much a machine amplifies the input force to produce the desired output force.
The mechanical advantage of the simple machine is 2, which is calculated as the output force divided by the input force (4n/2n = 2).
To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).
80 Is the Output force
mechanical advantage
The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.
The formula for finding mechanical advantage is MA = output force / input force. It represents the ratio of the output force to the input force in a simple machine.
Whatever output force is required, you can divide it by the "mechanical advantage" to calculate the input force.
