Numerical problems. In the given hydraulic press the cross
sectional area of cylinder A1 and A2 are
0.25m² and 8m² respectively, what magnitude
of effort is to be applied on cylinder A, to
balance a load of 1000N on the cylinder A1?

an energy transformation flow diagram is shown

where is it ?

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
