A horizontal boom is used to support the sign of a coffee shop. The boom itself is supported by a cable attached to one of its ends and its opposite end sits against and is supported by the wall horizontally by a normal force and vertically by friction. The coffee shop sign, originally supported by to ropes connected to the boom, is now precariously held by a single rope. The boom has a non-negligible mass. The system is in equilibrium (for the moment). Below is an illustration of the setup and a partially completed extended force diagram. Coffee House 0 WB TBS T a. Complete the force diagram by ensuring properly labeling and ensuring all forces have been included.

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and af…
