Forces In Truss Vocational Training Equipment Mechanical Experiment Equipment

I.Overview
This equipment is for mechanical engineering department or mechanics engineering department in university, it’s for Theoretical and Applied Mechanics, Engineering Mechanics, Solid Mechanics major and other mechanics related department.
This equipment allows measurement of axial forces in pin-jointed truss members and compare them with calculated values. It is to be used with Universal Structural Frame (separately supplied).
The truss consists of 19 members for construction of different cantilevered trusses where loading can be applied at any of the bottom joints by a load hanger and weights. An indicator measures truss deflection. The joints are designed to simulate pin-joints. Each truss member has a strain gauge. Each gauge is wired to form a full bridge with temperature compensation and zero adjustment in the strain indicator. A steady bar with three adjustable forks is provided to ensure lateral stability.
Instruction manual is also included.
