The right triangular truss is made of members having equal cross sectional area of $$1550$$ $$m{m^2}$$ and Young's Modulus of $$2 \times {10^5}\,\,MPa.$$

The horizontal deflection of the joint $$Q$$ is

A truss is shown in the figure. Members are to equal cross section $$A$$ and same modulus of elasticity $$E.$$ $$A$$ vertical force $$P$$ is applied at point $$C.$$

Deflection of the point $$C$$ is

A truss is shown in the figure. Members are to equal cross section $$A$$ and same modulus of elasticity $$E.$$ $$A$$ vertical force $$P$$ is applied at point $$C.$$

Force in the member $$AB$$ of the truss is

In a redundant joint model, three bar members are pin connected at $$Q$$ as shown in the figure. Under some load placed at $$Q$$, the elongation of the members $$MQ$$ and $$OQ$$ are found to be $$48$$ $$mm$$ and $$35$$ $$mm$$ respectively. Then the horizontal displacement $$'u'$$ and the vertical displacement $$'v'$$ of the node $$Q,$$ in $$mm,$$ will be respectively,
