The Parallel Spring Bracket allows springs to be combined in
series and parallel. Masses can be hung in offset positions to
compensate for springs of different strengths.
The Parallel Spring Bracket is ideal for:
•
exploring how spring constants add when springs are
arranged in series or in parallel,
•
demonstrating the analogy between combinations of springs
and combinations of capacitors, and
•
exploring torque acting on the hook bar by placement of the
mass and springs at different positions.

The table clamp (rather than a base) and a relatively short rod are recommended for maximum stabil-ity. 2. Hang any combination of springs from th...

Both springs have the same spring constant (40 N/m). The initial mass is p...

Spring #1 is attached at the axis, therefore its torque is zero. The net torque is (eq. 5) Solving for F s2 yields: (eq. 6) Combining equations 4 and ...
