Given the shape below, calculate the moment of inertia about the horizontal axis, which passes through the centroid of the cross section. Use b1 = 19, b1a = 13, t1 = 0.4, b2 = 10, and t2 = 0.5. Give the answer to one decimal place. t. bia b,

Q3-An 8-kg block is suspended from a spring having a stiffness K= 80 N/mlf the block is given an upward velocity of 0.4 m/s when it is 90 mm above its equilibrium position,determine the equation which describes the motion and the maximum upward displacement of the block measured from the equilibrium position. Assume that positive displacement is measured downward. Own=3.162 rad/s 0.031622 rad/s Own=31622 rad/s Own=0.31622 rad/s Own= 0.0375 rad/s
