3.The deflection y at the center of a circular plate suspended at the edge and uniformlykwd4loaded is given by y =where w= total load, d = diameter of plate, t =thickness and k is a constant. Calculate the approximate change inyif w isincreased by 3%, d is decreased by 2.5% and t is increased by 4%.answer: y decrease by 19% approximately

The values of z and y vary together at a constant rate of change such that Ay = 0.5Ar. (This information applies to all three parts.) %3D a, Suppose the value of r varies from z 1.5 to z -3. Your classmate comes to you after calculating the change in a for this interval: Ar = 0.5(-3 - 1.5) = -2.25 Are they right? (Select the one best choice.) ONo. They calculated Ay instead. ONo. They used addition instead of subtraction. ONo. They subtracted in the wrong order. O Yes. This is the change in z. b. Suppose the change in e between two points in this relationship is 5. Another classmate has calculated the corresponding change in y: Ay = 5 Are they right? (Select the one best choice.) ONo. This is the change in z. ONo. The change in y should be the same sign as the change in x. O No. They divided instead of multiplied. O Yes. This is the change in y.
