5-22. If the intensity of the distributed load acting on the beam is w=3 kN/m, determine the reactions at the roller A and pin B. 5-23. If the roller at A and the pin at B can support a load up to 4 kN and 8 kN, respectively, determine the maximum intensity of the distributed load w, measured in kN/m, so that failure of the supports does not occur.

5-22

### Problems 5-22/23

**5-22.** If the intensity of the distributed load acting on the beam is \( w = 3 \, \text{kN/m} \), determine the reactions at the roller \( A \) and pin \( B \).

**5-23.** If the roller at \( A \) and the pin at \( B \) can support a load up to \( 4 \, \text{kN} \) and \( 8 \, \text{kN} \), respectively, determine the maximum intensity of the distributed load \( w \), measured in \( \text{kN/m} \), so that failure of the supports does not occur.

### Diagram Description

The diagram shows a beam with two sections and a distributed load across part of it. The beam is supported at point \( A \) by a roller and at point \( B \) by a pin. The beam forms a \( 30^\circ \) angle at one section, with the following dimensions:

- The horizontal section connecting the roller \( A \) to the elbow is \( 3 \, \text{m} \) long.
- The slanted section connecting \( B \) to the elbow is \( 4 \, \text{m} \) long.
- The distributed load, denoted by \( w \), is applied on the slanted section ending at pin \( B \). 

Arrows representing the distributed load point downward, indicating the direction of the load's force.
