A rigid beam AB is hinged at A and is connected to an aluminium alloy bar BC at the other end. The beam is also supported on a steel post DE through a rigid bearing at D, as shown is figure. At no load condition, the beam is horizontal and there is an initial clearance 8 = 0.1 mm between the beam and rigid bearing.
