A 4.0-kg object is supported by an aluminum wire of length 2.0 m and diameter 2.0 mm. How much will the wire stretch?

A steel wire, 3.0 m long, has a diameter of 1.0 mm. If a 10 kg load is hung from the wire how far will it stretch? Young's modulus for steel is 2.0 × 10^11 pa

Orb Spiders make silk with a typical diameter of 0.15mm. 1)A typical orb spider has a mass of 0.50 g. If the spider suspended so from a single 12 cm long strand of self, by how much will the self stretch? 2)What is the maximum weight that a single strand of silk and support? 3)why do you have to lean forward when standing from a chair?

A vertical steel girder with a crosssectional area of 0.15 m2 has a 1550 kg sign hanging from its end. (Ignore the mass of the girder itself.) If the girder is 9.50 m long, how much is it lengthened? Note that the Young's modulus =200x10 9 * O 8.4x10 6m 4.4x10 -6m O 4.8x10 -6m O All answers are wrong

A 5.00 m -tall, 60.0 cm -diameter concrete column supports a 3.00×105 kg load. By how much is the column compressed?

A force stretches a (first) wire by 2mm. This wire is made of an unknown material and has a 1.2cm diameter and 3.5cm length. A second wire of the same material has the same length but four times the diameteras the first. How far will it be stretched by the same force?

A 5.73 kg pipe is hung from a steel wire that is 2.96 long and has a diameter of 0.839 mm. Young's Modulus for steel is 2.0x1011 N/m². By what distance does the wire stretch? Give your answer in millimeters.
