A hydraulic jack is used to lift objects such as automobiles. If the input force is 200 N over a distance of 1 meter, the output force over a distance of 0.1 meter is ideally
A)200 N.
B)500 N.
C)1000 N.
D)2000 N.
E)none of the above

Question

Quizplus · Accepted Answer

The output force of a hydraulic jack can be calculated using the formula Fout = Fin * (Din / Dout), where Fin is the input force, Din is the input distance, Dout is the output distance, and Fout is the output force. Plugging in the given values, we get Fout = 200 N * (1 m / 0.1 m) = 2000 N. Therefore, the output force over a distance of 0.1 meter is 2000 N, which is option D.
