Draw the correct bond graph, first the unsimplified one, then simplify it$.$

a$)$ Work each homework problem in an organized and clear way.

b$)$ Label all $0-$junctions and $1-$junctions with a corresponding effort or velocity.

c$)$ Always show intermediate steps before simplifying the bond graph.

d$)$ Indicate the causal strokes using the rules studied in class, trying to use integral causality.

e$)$ Apply primary and secondary conditions to determine and clearly indicate the effort and flow in

each power bond. Remember that at the end, each effort and flow can only be a function of the

inputs and the variables that have a dot as first derivative at the C and I elements.

f$)$ Find the set of first order differential equations that represent the mathematical model of the

system.
