$10-29.$ Determine the force in each member of the truss.

Assume the members are pin connected at their ends. $AE$ is

constant.

$10-35.$ The trussed beam supports the uniform distributed

loading. If all the truss members have a cross$-$sectional

area of $750m{m}^2,$ determine the force in member $BC.$

Neglect both the depth and axial compression in the beam.

Take $E=200$GPa for all members. Also, for the beam

$I_{AD}=300({10}^6)m{m}^4.$ Assume $A$ is a pin and $D$ is a rocker.
