LINEAR ARCH MODEL
It is a simple device to draw the line of thrust in archs for a given systems of loading. A flexible string is taken whose one end is tied to a pin on a vertical board the other end of the string passes over a smooth pulley fixed to the same vertical board .The distance between the pulley and pin can be adjusted to . it , in which known weights can be put . There is an arrangement to suspend any given loads from the any given loads from the string between the pin and the pulley for any given values of the loads on the string as well as on the pen, the string will maintain equilibrium in a certain deflected form. The deflected form of the string will then represent linear arch for a give systems of loading. The linear arch will change its shape if the load in pan is changed. The load in the vertical components of this tension in the string at pulley end. The vertical component of this tension in the string are always the same and only depends upon the magnitude and location of the applied to the string. However its horizontal component changes with the weight in the pan. Thus linear arches with the different horizontal components changes with the weight in the pan. Thus linear arches with the different horizontal reaction at the end can be constructed with same systems of loading.
