The light (i.e., massless), rigid bar is pinned at O as shown
in the figure. The system undergoes small oscillations in
the vertical plane under the action of the force F(t). At
spring 1
t= 0, the system is in equilibrium in the configuration
massless, rigid bar
spring 2
shown. Note that the spring 1 is stretched by A in this
static equilibrium configuration. Note also that the spring 2
is unstretched in this static equilibrium configuration.
