AFME019 Redundant Truss

AFME019 Redundant Truss

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.
The equipment allows measurement of deflections and axial forces in pin-jointed truss members when a redundant member is added. It is to be used with Universal Structural Frame (separately supplied).
A wall mounted truss frame has a pinned upper joint and the lower joint a roller bearing on a support. There are 7 truss members and an extra member with an adjustable length. Load is applied by a load hanger and weights. Deflection is measured by a dial indicator. Each truss member has a strain gauge which is wired to form a full bridge with temperature compensation and zero adjustment in the strain indicator.
Instruction manual is also included.
II.Typical Experiments
Study of strains, stresses, forces and deflections in a statically determinate and indeterminate structure
Force analysis by Method of Joints
Force analysis by the use of the strain energy method.
III.Technical Data
Structure: aluminum
Bottom with adjustable rubber to adjust the height.
The total weight is less than 200kgs.
Working environment: -10℃~40℃, Humidity<85%
