Equilibrium of Rigid Bodies | Rotation Restricted but Vertical Movement Allowed

This channel is an avenue to share my knowledge on various subjects such as mathematics, literature, and research, but I mainly focus on Civil Engineering Subjects.

Not all problems will be accommodated, but items sent will be curated to discuss the necessary topics that students need help with.

Playlists:

For the beam shown, an additional concentrated moment load (clockwise) is applied at the propped end with a magnitude of 1200 kN-m and a uniform load of 40 kN/m is applied at the entire span. If P = 100 kN and L= 8 m,
