A trolly of 10,000 kg is placed on a platform which is fixed to a press piston of a hydraulic lift. The areas of cross section of the press piston and pump piston are 72 m2 and 0.6 m2, respectively. Arrange the following steps in a proper order to find the effort applied on the pump piston and mechanical advantage of hydraulic lift by using load and effort.
(A) Pressure is equal on both the press and pump pistons, i.e., P1=P2 or a1F1=a2F2.
(B) Find the mass of the trolly, areas of cross section of pump piston and press piston from the given data.
(C) The force on the press piston (F2) is equal to weight of the trolly, this is the load.
(D) The amount of force (F1) needed to be applied on the pump piston to lift the trolly is effort.
(E) The mechanical advantage of the hydraulic machine is the ratio of load to effort.

(B) Find the mass of the trolly, areas of cross section of pump piston and press piston from the given data.
(C) The force on the press piston

(F_{2})

is equal to weight of the trolly, this is the load.
(D) The amount of force

(F_{1})

needed to be applied on the pump piston to lift the trolly is effort.
(A) Pressure is equal on both the press and pump pistons, i.e.,

P_{1} = P_{2}

or

\frac{F _{1}}{a _{1}} = \frac{F _{2}}{a _{2}}

.
(E) The mechanical advantage of the hydraulic machine is the ratio of load to effort.

Question Text	A trolly of $10, 000 kg$ is placed on a platform which is fixed to a press piston of a hydraulic lift. The areas of cross section of the press piston and pump piston are $72 m^{2}$ and $0.6 m^{2}$ , respectively. Arrange the following steps in a proper order to find the effort applied on the pump piston and mechanical advantage of hydraulic lift by using load and effort. (A) Pressure is equal on both the press and pump pistons, i.e., $P_{1} = P_{2}$ or $\frac{F _{1}}{a _{1}} = \frac{F _{2}}{a _{2}}$ . (B) Find the mass of the trolly, areas of cross section of pump piston and press piston from the given data. (C) The force on the press piston $(F_{2})$ is equal to weight of the trolly, this is the load. (D) The amount of force $(F_{1})$ needed to be applied on the pump piston to lift the trolly is effort. (E) The mechanical advantage of the hydraulic machine is the ratio of load to effort.
