Problem $3$

Three forces act on the shown structure, which is in equilibrium.

a$)$ Find the magnitude of the force $F_3$

b$)$ Find the forces $R_H$ and $R_v$ at the pivot

Neglect the weight of the structure.

Additional Practice Problem

The beam is subjected to $F_1=25N$ inclined at an angle ${45}^0$ with the horizontal and a vertical load $F_2=23\mathrm{.}5$ N $.$ The beam is in equilibrium.

a$)$ Find the torque at the pivot due to the force $F_1$ and indicate its direction.

b$)$ Find the distance $d$

c$)$ Find the magnitude of the horizontal and vertical forces at the pivot and their direction.

$F_1=25$
