The platform is rotating such that, at any instant, its angular position is 0 = (0.21t³ -0.22t² + 3) rad, where t is in seconds. A ball rolls outward so that its position is r = (0.57t³) m. Find the magnitude of the acceleration of the ball in m/s² when t = 1 seconds. Round your answer to 3 decimal places

The paper is 1.0 mm thick and the tube has an outer diameter of 100 mm. Determine the shear stress acting along the seam, which is at 50° from the horizontal, when the tube is subjected to an axial compressive force of 200 N.
