Apparatus consists of a mild steel angle of size 1" X 1" X 1/8" or an equivalent metric units of length 80 cm is tied as a cantilever beam. The beam should be fixed at one end such that the rotation of 45degree intervals are given and clamped such that the principal axis of its cross-section may be inclined at any angle with the horizontal and vertical planes. Also arrangement will be provided to apply vertical load at the free end of the cantilever and to measure horizontal and vertical deflection of the free end. A dial gauge with 25mm travel (with magnetic base) will be supplied with the apparatus. Apparatus will be supplied complete with a supporting stand and a set of weights
