The bell crank system shown
in the figure below is attached
to a horizontal spring BC with
stiffness k = 2 kN/m and a pin
support at point A. Spring BC
is unstretched when angle 𝜃 = 0°,
and the bell crank is in equilibrium
under the effect of the external
force F when angle 𝜃 = 15°. If
spring BC remains in a horizontal
position at all times due to the
roller at C, determine the following
when the crank is in equilibrium:
a) the change in length of spring BC
when the crank rotates about point A
and angle 𝜃 goes from 0° to 15°, and
the resulting force in the spring Fs.
b) The horizontal and vertical support
reactions at pin A when angle 𝜃 = 15°.
