A stranded steel cable with known cross section and modulus of elasticity supports a 950 lb gin pole. As the gin pole is descending at a constant velocity, an accident causes the top of the cable 70 ft above the gin pole, to suddenly stop. Estimate the maximum elongation and maximum tensile stress developed in the cable. Steel cable A = 0.110 in. psi E = 12 x 10° psi Gin pole v = 30 fpm
