Question

Determine the following beam.

1) Determine the reactions at the supports.

2) Determine the magnitude and location of the max bending moment.

3) provide a shear and bending moment diagram for the beam.

The image depicts a structural beam analysis diagram involving various loads and supports.

1. **Beam and Supports**:
   - The beam is supported at two points. The left support is a triangular representation of a pin support, providing both vertical and horizontal reaction forces. The right support is a roller support shown with a triangle atop a rectangle, providing only vertical reaction forces.

2. **Loads**:
   - At the far left end of the beam, there is a concentrated load of 100 lbs.
   - Along the beam, there is a uniformly distributed load of 25 lbs/ft extending over a specified section.
   - At the far right end, a concentrated load of 75 lbs is applied.

3. **Beam Dimensions**:
   - The distances between various loads and supports are marked: 
     - From the left end to the roller support, the distance is 4 feet.
     - Between the portions of distributed load and points where measurements are not labeled, indicate sections are 3 feet and 4 feet, as shown.

This diagram is typically used in structural engineering to determine reactions at supports and internal stresses such as shear forces and bending moments across the beam.
