A two hinged semi-circular arch of radius R carries a concentrated load W at the crown. The horizontal thrust is

A three – hinged parabolic arch rid of span L and crown rise ‘h’ carries a uniformly distributed superimposed load of intensity ‘w’ per unit length. The hinges are located on two abutments at the same level and the third hinge at a quarter span location from the left-hand abutment. The horizontal trust on the abutment is:

In a two-hinged parabolic arch (consider arch to be initially unloaded) an increase in temperature induces -

While fabricating a square truss, the member BD was somehow defectively short (fabrication defect) as shown in the figure. So stress developed in the member AC immediately after constructing the truss by force would be
