Rod in Static Equilibrium#
The figure shows a mass \(M\) attached to the right end of a rod of length \(L\) and of mass \(m\). There is a support located at the middle of the rod. The left end of the rod is connected to a spring. The system is in static equilibrium.
Part 1#
Determine the magnitude of the vertical force exerted on the rod by the spring (\(F_S\)).
Use the following table as a reference for each variable. Note that it may not be necessary to use every variable.

Answer Section#
Please enter in a symbolic value in \(N\).
Part 2#
Determine the direction, \(\theta\), of the vertical force exerted on the rod by the spring (\(F_S\)). Assume that the left end of the rod is at the origin of a Cartesian plane (\(\theta > 0\) with zero being to the right).
Answer Section#
Please enter in a numeric value in degrees.
Part 3#
Find the magnitude of the normal force exerted on the rod by the support (\(n\)).
Use the following table as a reference for each variable. Note that it may not be necessary to use every variable.
