Estimate the roll force and total power for annealed low-carbon steel strip 200 mm wide and 10 mm thick, rolled to a thickness of 6 mm. the roll radius is 200 mm, and the roll rotates at 200 rpm. let μ = 0.1. compare this high frictional force and power with the low frictional forces and power. the values of k and n are 530 mpa and 0.26, respectively.

Let f(x) = x4- 8x2 . find the relativeextrema of this function using the second derivative test.

What is the final velocity of the initial velocity of 25 and -50?
