Forced undamped vibrations

In mechanical engineering, vibration is expressed as the term that occurs due to an object's backward and forward movement about a point of equilibrium. Generally, there are three types of vibrations which are,

Question

Learning Goal:
To use the equations of equilibrium to analyze a system
containing a wedge and to determine the necessary
applied force to introduce motion into the system.
The crate shown is held against wedge B by a spring. The
spring is 94.0% of its original uncompressed length
1 = 3.00 m, and the spring constant is given as
k = 1650 N/m. The coefficient of static friction at all
contacting surfaces is μs = 0.100. The mass of the crate
is m = 25.0 kg . The angle is 0 = 14.0°. Neglect the
mass of the wedge. Assume the crate only moves in the y
direction and that wedge A cannot move. (Figure 1)
