A steel telephone wire 125 m long and 1 mm in radius isstretched to 125.15 m by an
applied force of 800 N. (The weight of the cable may beignored.)


a. What is the elastic modulus of steel ?
b. What is the maximum force that can be applied to the wire,without it breaking?
c. How long will the wire be in part (b) ?
d. How thick will the wire be when 1200 N is applied ?


Assume a Tensile Strength of 500000000 Pa

and Poisson’s ratio of0.28 for steel

A circuitconsists of two 1.5-volt batteries and two Nichrome wiresofdi?erent lengths and di?erent thicknesses. The thick wireis 51 cmlong, and its diameter is 0.19 mm. The thin wire is15 cm long, andits radius is 0.13 mm. The electron mobility inroom-temperatureNichrome is about 7e-5 (m/s)/(N/C), andthere are about 9e28 mobileelectrons per cubic meter inNichrome.

5.19 .. CP A 750.0-kg boulder is raised from a quarry 125 m deep by a long uniform chain having a mass of 575 kg. This chain is of uniform strength, but at any point it can support a maximum tension no greater than 2.50 times its weight without breaking. (a) What is the maximum acceleration the boulder can have and still get out of the quarry, and (b) how long does it take to be lifted out at maximum acceleration if it started from rest?
