Answer

40 \text{ kN}$ downwards at the top-left joint (J1).

Step 1: Identify the supports and external forces. The frame has a roller support at the bottom-middle joint (let's call this J5) and a pin support at the top-right joint (let's call this J3). External forces are:

$F_1 = 40 \text{ kN}$ downwards at the top-left joint (J1).
$F_2 = 50 \text{ kN}$ downwards at the top-middle joint (J2).
$F_3 = 50 \text{ kN}$ downwards at the top-right joint (J3).

Step 2: Determine the geometry of the frame. The problem states that internal angles are $45^\circ$ .
