- Homework Statement
- Determine the horizontal and vertical components of reaction on the

beam caused by the pin at B and the rocker at A as shown in Fig. 5–12a.

Neglect the weight of the beam.

- Relevant Equations
- M = Fd

Hi all,

Why was the thickness of the beam considered when moment was being calculated and why was the horizontal component of the 600 N force used in calculating the moment? That part is unclear to me. Please explain it. Am I looking for the logic behind using the horizontal comp. and the thickness value for moment. Are we saying that a force applied at an angle causes some change in thickness of the beam? Please see attached picture below
