The effective length of a compression member of length L held in position and restrained in direction at one end and effectively restrained in direction but not held in position at the other end, is
L
0.67L
0.85L

For determination of allowable stress in axial compression, Indian Standard Institution has adopted
Euler's formula
Rankine formula
Engesser formula
Secant formula
Number of bolts required in a bolted joint is equal to
Force / Bolt value
Force / Strength of bolt in shearing
Force / Strength of bolt in bearing
Force / Strength of plate in tearing
Shape factor is a property which depends
Only on the ultimate stress of the material
Only on the yield stress of the material
Only on the geometry of the section
Both on the yield stress and ultimate stress of material
