Two Pinned Arch Unit Model MT 051
Two Pinned Arch Unit Model MT 051
Sci-tech Two Pinned Arch Unit Model MT 051 enables to determine experimentally the horizontal component of the abutment thrust of a two hinged arch beam.
The beam is supported on ball bearing rollers attached to each end of the beam and the horizontal movement of the free end is indicated by a dial gauge so that the beam can be returned to it’s original unloaded span.
The horizontal thrust force is applied to the free end of the beam by means of masses or weights attached to a cord passing over the ball bearing pulleys.
Varying loads can be applied to the beam by means of load hangers and masses. A dial gauge enables to measure the vertical displacement.

Item Description
One of the main problems in the study of loads distribution on horizontal beams is related to vertical loads. Such loads, transverse to the beam direction, can generate bendings, with the consequent breaking risk. The greatest advantage of arched beams is that they are able to distribute these vertical loads between an horizontal and a vertical component, so that the total load in the vertical axis is reduced, and the breaking possibilities diminish.
This is applicable when big spans must be covered with only two support points. The arched beam has the advantage of supporting greater vertical loads than a straight beam, which can present, in this cases, great bending signs.
