=

If support Q settles by units, what is the reaction at Q?

Question 6

A linear elastic structure is loaded at 5 coordinate location, such that [F]T ={100, -75, 150, 200, -250} kN. The corresponding deflections [D] at these coordinates are {5, -8, 7, 5, -4} mm. If in a separate loading condition in which P4 alone acts, the observed deflections are {1, 2, -3, 4, -2} mm. The value of P4 is _________ kN (nearest integer).
