A lightning bolt strikes one end of a steel lightning rod, producing a 14500-A current burst that lasts for 65 . The rod is 2.5 long and 2.1 in diameter, and its other end is connected to the ground by 38 of 8.1-mm-diameter copper wire.
A. Find the potential difference between the top of the steel rod and the lower end of the copper wire during the current burst.
(answer in volts, V)
B. Find the total energy deposited in the rod and wire by the current burst.
(answer in joules, J)
Either or

Acylindrical specimen of a nickel alloy having an elastic modulus of 207 gpa (30 × 106psi) and an original diameter of 10.2 mm (0.40 in.) experiences only elastic deformation when a tensile load of 8900 n (2000 lbf) is applied. compute the maximum length of the specimen before deformation if the maximum allowable elongation is 0.25 mm (0.010 in.)

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
