Transcribed Image Text:1. Equilibrium Lab Example.
A meter stick with unknown mass is suspended by two strings of length 60 cm each, so that it
forms an equilateral triangle, 30 cm from the center on each side of stick as shown. Three
masses, mass 1= 200g, mass 2= 400 g, and a third unknown mass are hung at 3 different
positions as shown (mass 1 at 50 cm meter stick position, mass 2 at the 20 cm position, and
mass 3 at the 90 cm position 10 cm from left). The system is in static equilibrium, tension, T of
the top string is 10N, and the center of gravity of the meter stick of unknown mass is in the
center.
