Forces in an Overdeterminate Truss

Forces in an Overdeterminate Truss

Product Details:


Product Description


With Surplus Bars A Statically Determinate Truss Becomes Internally Statically Indeterminate. In This Case The Truss Is Termed Statically Overdeterminate. In An Overdeterminate Truss, The Bar Forces Depend On The Elastic Properties Of The Truss And Cannot Be Calculated Easily. The Experimental Setup Permits Investigation And Comparison Of Statically Determinate And Statically Indeterminate Trusses. Using The Bars And Node Disks, A Statically Determinate, Single Plane Truss Is First Constructed. On Installation Of A Surplus Bar The Truss Becomes Overdeterminate. By Way Of A Load Application Device, Straight Or Inclined Forces Are Applied To The Truss, Thereby Simulating Various Load Cases. The Occurring Tensile And Compressive Forces In The Bars Are Recorded By Means Of Strain Gauge Measurement.
