A steel rod of radius R =15cm and length lo stands upright on a firm surface. A 65-kg man climbs atop the rod.(a) Determine the percent decrease in the rod’s length.(b) When a metal is compressed, each atom moves closer toits neighboring atom by exactly the same fractional amount.If iron atoms in steel are normally 2.0x10-10 m apart, bywhat distance did this interatomic spacing have to changein order to produce the normal force required to supportthe man? [Note: Neighboring atoms repel each other, andthis repulsion accounts for the observed normal force.]

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?
