FF-1111 Toggle Joint Apparatus

Experiments

  • Force resolution on a toggle joint.
  • Distribution of forces and reaction forces on a loaded toggle joint.

Description

This unit is designed to study the characteristics of toggle joint. Toggle joint is a structure which has three members connected in a triangular shape. Two of its members have fixed lengths but third member (base member) has a variable length. Its length can change due to the load applied at the top of the triangular structure.

The unit consists of a metallic base structure which provides the support locations for the structure. Three members are connected in a triangular shape to form a toggle joint. The base structure is fixed at one end but its other end is movable. It has a spring balance which shows the elongation and hence the force acting on movable end due to the load applied on the top of the structure via a hanger.
