a 300 kg cylinder that is horizontal. Three steel wires support the cylinder from a ceiling.Wires 1 and 3 are attached at the ends of the cylinder, and wire 2 is attached at the center. The wires each have a crosssectional area of 2.00 * 10-6 m2. Initially (before the cylinder was put in place) wires 1 and 3 were 2.0000 m long and wire 2 was 6.00 mm longer than that. Now (with the cylinder in place) all three wires have been stretched.What is the tension in (a) wire 1 and (b) wire 2?

Hi please help: An 88kg person stands on a uniform 5.6kg ladder that is 4.0m long. The floor is rough, hence, it exerts both a normal force, f1, and a frictional force, f2, on the ladder. The wall, on the other hand, is frictionless, it exerts only a normal force, f3. Using the dimensions given, find the magnitude of f1, f2, and f3. Express answer using two significant figures and as kN as units.
