Figure Q19
Finding the vertical reactions is the starting point which can be done by taking moments at A and G but since this is symmetrical loading case the vertical reactions can simply be calculated by halving the total loading 4 kN.
Ideally, we can solve the problem using the Method of
cutting through the members JK, DJ and
It would be sensible to select the left-hand side of the diagram as there are less full members and only one force from the reaction at node A.
This will expose the internal forces which can be labelled with the names of the members themselves.
Since we are required to find JK, examining the framework shows it is not a straight-forward matter, and we will require finding all three unknown internal forces.
The easiest internal force to find is
Next, we can take moments at node
, as we can resolve forces in the vertical direction.
in order to find the internal force JK and find…

To find the reactions the starting point is to take moments at a suitable node location. Since node unknowns it is the ideal location to first take moments. By taking moments in a clockwise orientation we find a moment of there is an additional moment of 288 kNm from the load at C. From combining all moments together, we can then find the vertical reaction at F which is RFy= place. For best practice, it is a good approach to take moments at has two kNm due to the force load at node B and KN to 1 decimal in order to the find the vertical reaction RAY- Finally, we can sum forces in the horizontal direction to find the reaction RAX = -72 kN, assuming the reaction at A acts left-to-right. After which we can then sum forces in the vertical direction to verify the sum of RAY plus Rgy is the same as the total downwards force which should be KN.arrow_forward
