Basically plot a graph of axial tension against position along shaft . Have a try .

What do you mean? can you explain further?

If you do a force balance on the entire rod, what do you get for the reaction force on the left end?

how to do it ? i know only the P3 .... which is 120kN , how to do for P1 and P2 ?If you do a force balance on the entire rod, what do you get for the reaction force on the left end?

You have 3 forces acting on the rod: 300 kN, 180 kN, and 120 kN. In order of the rod to be in static equilibrium, there must also be a force applied by the wall on the bar at location A. What does that force have to be?how to do it ? i know only the P3 .... which is 120kN , how to do for P1 and P2 ?

what i found is this ? how to find the force applied by the wall on the bar at location A. ??You have 3 forces acting on the rod: 300 kN, 180 kN, and 120 kN.

btw , i am not sure which 1 is P3 and which one is P2

Forget about P1, P2, and P3 for now. Are you saying that you don't know how to do a 1 dimensional equilibrium force balance on a solid object?what i found is this ? how to find the force applied by the wall on the bar at location A. ??

F = 300 -180 + 120
