Question
Robert invented a machine that would do his work for him. His machine used 5.6 N and produced 11 N. Whatis the mechanical advantage of this machine?
Solution 1
The mechanical advantage of a machine can be calculated using the formula:
Mechanical Advantage = Output Force / Input Force
In this case, the output force (the force produced by the machine) is 11 N and the input force (the force used by the machine) is 5.6 N.
So, the mechanical advantage of the machine is:
Mechanical Advantage = 11 N / 5.6 N = 1.96
Therefore, the mechanical advantage of Robert's machine is 1.96.
Solution 2
The mechanical advantage of a machine can be calculated using the formula:
Mechanical Advantage = Output Force / Input Force
In this case, the output force (the force produced by the machine) is 11 N and the input force (the force used by the machine) is 5.6 N.
So, the mechanical advantage of the machine is:
Mechanical Advantage = 11 N / 5.6 N = 1.96
Therefore, the mechanical advantage of Robert's machine is 1.96.
