1. The problem statement, all variables and given/known data A tow truck is pulling a car out of a ditch by means of a steel cable that is 9.1 m long? and has a radius of 0.50 cm .when the car just begins to ,move , the tension in the cable is 980 N. how much has the cable stretched? Y steel= 2.0 x 10¹¹ N m² 2. Relevant equations F/A = Y (delta L / L0 ) 3. The attempt at a solution We just need to solve for delta L, but I am having difficulty figuring out what A would be - any help? What A formula for the cable do I use?
