Fluid mechanics

Question

The largest helicopter in the world, which was built in Russia, has a mass of 1.03 x 10³ kg. If you placed this helicopter on a large piston of a hydraulic lift, what force would need to be applied to the small piston in order to slowly lift the helicopter? Assume that the weight of the helicopter is distributed evenly over the large piston’s area, which is 1.40 x 10² m². The area of the small piston is 0.80 m².

Answer 1

Hi John!

 

This question follows the same path as the other hydraulic lift question, except that you have to calculate the weight of the helicopter rather than have it given.  Other than that, it is identical, so take a look at the other hydraulic lift problem, and if you have any questions, just let me know!
