Problem 3:As shown, a mouse can use the mechanical advantage provided by a hydraulic machine to lift up an elephant.a. Derive an algebraic equation that gives the mechanical advantage of the hydraulic machine shown. Assume the pistons are frictionless and massless.b. A mouse can have a mass of 25 g and an elephant a mass of 7500 kg. Determine a value of D1and D2 so that the mouse can support the elephant.
