All of the above
length and least radius of gyration of the column
area of cross-section of the column
modulus of elasticity for the material of the column
A three hinged arch is loaded with an isolated load 1000 kg at a horizontal distance of 2.5 m from the crown, 1 m above the level of hinges at the supports 10 metresapart.

25mm
The materials which have the same elastic properties in all directions, are called
homogeneous
hard.
Isotropic
Brittle
The relation between equivalent length (L) and actual length (l) of a column for both ends fixed is
l = 2L
L = l
L = l/2
Rivets are generally specified by
diameter of head
thickness of plates to be joined
overall length
shank diameter
A joint of a frame is subjected to three tensile force P, Q and R equally inclined to eachother.
If P is 10 tonnes, the other forces will be
Q = 10 tonnes and R = zero
Q and R each is equal to 10 tonnes.
Q - R = zero
Q + R = 10 tonnes
R + 10 tonnes and Q = zero
