Folks...He is professor at IIT - Premier institute in India. It is very coveted position in India and competition is fierce. Most of the time, these professors complete their PHDs in US and come back. I studied at IIT. Students from IITs go on to have very successful careers due to the solid foundation.

If you write u1 and u2 instead of ui and uj, and write F1 and F2 instead of Fi, Fj, you can easily interpret the physical meaning that " kij is the force that has to be applied at j in order to have unit displacement at I"

Question : at the end of the day isnt the fixed point just having an equivalent force to the opposite side of the force ? Why can't we put the force there ?

@janakamohotti 3 жыл бұрын

because there is no displacement at the fixed point. F=ku. when u is zero, the force there will be zero as well

@janakamohotti 3 жыл бұрын

He clearly stated that only the external forces are considered in the force matrix. (bcz internal forces are created and balanced itself by the system)

Ui & Uj have taken based on one end fixed condition - @ 11:50 And @13:20, professor took a force matrix, for stepped shaft and told the above forces to be super positioned, If we apply super position principle Ui & Uj have to take positive as they are not resistive displacements.

@sakonpure6 7 жыл бұрын

How? Can you elaborate - When you multiply row 1 , you get k1*0 + -k1*u2 + 0*u3= F1 which implies F1=-k1*u2

@marikagabbianelli 6 жыл бұрын

there are no external forces applied at nodes 1 or 2 - fr this reason f1 and f2 will both be 0. the only external force is applied at node 3 which is why f3=p

@akshay6135 6 жыл бұрын

Anjan: see the figure.. In the fig there are 3 node .. the nod 1 is at fixed end .. so the displacement at the fixed end become zero{u1=o}

It affects other equation (ie for F2 and F3) in no way....each time the u1=0 will make its term zero.

@bvk9686 4 жыл бұрын

Because node 1 was fixed so there could be zero displacement in position of node 1. So displacement u becomes 0 and when u solve the matrix 1st row and column do get multiplied with 0 that gives the ans 0 only. So to save time we just eliminate the row n column as it's no use to continue with them
