If you are asked to solve this problem using two node two elements, explain how will distribute the point load on the nodes?

Solution

If you are using two noded two elements, the best way is to place the intermediate node at the point of application of the concentrated/point load. Thus the first elements will be of length 5 m whereas the second element will be of 1 m. In that case the load will be completely applied at the intermediate node.

If you equally divide the two elements i.e., both elements are of length 3 m, then you can proportionately divide the load at two nodes that is, the node at x = 3 will be applied a load of 24*1/3 = 8 N and the node at x = 6 will be applied a load of 24*2/3 = 16 N
