For permissible shear stress fs, the torque transmitted by a thin tube of mean diameter D and wall thickness t is
The strain energy stored in a spring when subjected to greatest load without being permanently distorted is called
A concentrated load P is supported by the free end of a quadrantal ring AB whose end B is fixed. The ratio of the vertical to horizontal deflections of the end A is
An isolated load W is acting at a distance 'a' from the left-hand support of a three-hinged arch of span '2l' and rise 'h' hinged at the crown. The vertical reaction of the arch is
