Toggle Joint (SMT-MM-23)

availability: in stock

Determines the horizontal reaction due to loading a
toggle joint mechanism; assesses the effect of the
toggle angle.
The apparatus consists of two pair of links mounted
on a base with one end of the links fixed, a central
pivoted joint, and the other end restrained by a
spring balance to read the resulting horizontal force.
Loading applied at the apex pivot by a weight hanger.
Variable toggle angles available, and facility to readjust to original state.
Technical specification

- +


This apparatus is designed to evaluate forces within a toggle mechanism. Load is applied to
the two pairs of links by a hanger suspended from their connecting pivot. One end of the
links is pivoted to a base, and the other end is able to move sideways on low friction ball
bearing wheels. The moving links are restrained by a horizontal spring balance, which
measures the horizontal reaction directly. The angle of the toggle can be varied. Adjustment
is provided for returning the geometry of the loaded toggle to its original unloaded state
before taking measurements. The supporting blocks are not supplied.
