Description
The apparatus includes a free standing back plate mounted on a worktable, 3 wires at different angles, load hangers, weight and a universal ring. Wire suspension scheme is used to verify the equilibrium where sum of horizontal and vertical forces are zero.
Three wires attached at 45 degree; 60 degree and 90 degree meet at common ring. Load hanger is attached to the universal ring. Each wire includes a linear spring balance to get the value directly. Length of each suspender can be adjusted with the help of threaded rod attached to the spring balance. Known weights are available to apply load to the wires.
