Seeking help here I'm revising for my Continua finals this friday, and I am extremely weak in this area.... Encountered this Conservation of Energy problem and I hope someone may be able to help me before doomsday this Friday
-----------------------
A small block of rubber, dimensions L1, L2 and L3, is sandwiched between two electrodes. This rubber is subjected to external forces F1, F2 and F3 and a voltage V. See figure below.

The forces produce displacements d1, d2, d3 respectively, and charge Q is deposited on the electrodes due to the voltage.

The total energy density in the rubber may be written as a function
,
where .

Assuming the thermal energy remains constant, what is the energy balance equation for this system?

What is the relationship between F1, F2, F3, V and the energy density W?

Given that
where k and are constants,
obtain explicit relations between the work conjugates.
-----------

I'm overwhelmed by the question!!! Help me please!
