In (Figure 1), d=0.512 in. and dy = 0.8 in. y y³ = x dy x dx Determine the moment of inertia of the area about the x axis. Express your answer in inches to the power of four to three significant figures.

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

1. The following equation describes the relationship between the maximum deflection of the end of a beam and the applied load. PL3 = 3EI a) If ð is the maximum deflection in inches, L is the length of the beam in inches, P is the load in pounds, and E is the Young's Modulus in pounds/in?, find the units for I (moment of inertia). b) The measured deflection for a specific beam under loading is measured to be .01 in. Convert this to millimeters.
