If the M.I of section about its axis is I and if the effective sectional area is A, then radius of gyration r is given by

The moments in the arch will be zero, if

The stiffness factor at the near end of a member with far end hinged is

The load, required to produce a unit deflection in a spring is called:

The theorem of three moments for the solution of continuous beams is formulated by

The shear force and bending moment are related by

The arch meant for supporting uniformly distributed loads, to avoid any bending moment must be

If the co moment of Joint A, B, & C are 10, 20 and 30 kN-m then find the balancing moment at joint B.

Elasticity of a body is defined
