The drawing shows an A-shaped ladder. Both sides of the ladder are equal in length. This ladder is standing on a frictionless horizontal surface, and only the crossbar (which has a negligible mass) of the "A" keeps the ladder from collapsing. The ladder is uniform and has a mass of 16.6 kg. Determine the tension in the crossbar of the ladder. Number i Units 30.0% 4.00 m Crossbar 1.00 m/
